TSH stands for thyroid stimulating hormone, a hormone produced by the pituitary gland that stimulates the thyroid gland to produce hormones that affect metabolism. TSH imbalances may lead to fatigue, weight gain, sensitivity to cold, joint and muscle pain, dry skin, dry or thinning hair, heavy or irregular menstrual periods, depression, constipation, numbness and tingling in the hands, decreased interest in sex, slow heart rate, puffiness in the face, hair loss, infertility, osteoporosis, mood swings, dry skin, constipation, and/or hair loss.

A T3 (triiodothyronine) test is a blood test that helps diagnose thyroid conditions, specifically hyperthyroidism. Hypothyroidism is when the thyroid overproduces hormones, causing symptoms such as a fast heart rate, weight loss, trembling, and sweating.

A free T4 test is used to find out how well your thyroid gland is working. It is often used to find out whether someone has hyperthyroidism, which means an overactive thyroid, or hypothyroidism, which means an underactive thyroid.

A high-sensitivity C-reactive protein (hs-CRP) test is a blood test that measures low levels of C-reactive protein (CRP) in the blood. CRP is a protein produced by the liver in response to inflammation. High and low levels of CRP are often associated with hormone imbalances.

The test helps evaluate how much insulin your pancreas is producing and can be used for a variety of purposes, including screening for diseases like diabetes, prediabetes, and gestational diabetes, insulin resistance, low blood glucose, and hormone conditions like polycycstic ovary syndrome (PCOS).

Ferritin is a protein in cells that stores iron, which your body uses for many functions, including the formation of red blood cells and oxygen transport. Low ferritin levels can indicate iron deficiency, which can lead to anemia. High ferritin levels can indicate conditions like inflammation, obesity, or hemochromatosis. Ferritin levels can also often explain fatigue, hair loss, and hedaches.

HDL cholesterol is sometimes called "good" cholesterol, and high levels may lower the risk of heart disease. HDL levels can often shift as a result of hormone imbalances.

LDL cholesterol, or "bad" cholesterol, testing measures the amount of LDL cholesterol in your blood. LDL cholesterol levels can be affected by several hormones, including estrogen, AMH, and cortisol. When levels are too high, it can cause the formation of plaque buildup in the arteries.

Total cholesterol numbers are part of a risk assessment for heart disease. Too much cholesterol in the blood can damage arteries and blood vessels and elevate risk for stroke, heart attack, and heart disease. Cholesterol is a fatty substance produced by the liver to help thousands of bodily functions, such as building cells, promoting hormone and brain function, and synthesizing Vitamin D. Cholesterol also serves as a building block for many hormones, including sex hormones like estrogen and testosterone, and glucocorticoids like cortisol.

Triglycerides are a type of fat, or lipid, that are the most common type of fat in the body. The body uses triglycerides for energy between meals and stores them in fat cells when calories aren't needed immediately. Hormones are responsible for releasing triglycerides for energy.

VLDL is a type of lipoprotein that the liver produces and releases into the bloodstream. Dysregulated VLDL can be correlated with cardiovascular disease, and hormone imbalances can impact VLDL in a variety of ways.

A hemoglobin A1C (HbA1c) test, also known as an A1C test, measures the average blood sugar levels over the past three months.  It diagnoses, monitors, and screens for prediabetes and diabetes - and therefore is  used to assess hormone imbalances, especially polycystic ovary syndrome and infertility.

The 25-hydroxy vitamin D test is the most accurate way to measure how much vitamin D is in your body. Vitamin D helps control calcium and phosphate levels in the body. It regulates the production and activity of estrogen and progesterone, and can help ease and prevent hormonal fluctuations. Vitamin D can also help with menopause symptoms like joint pain and poor immune function.

Basophils respond to allergic reactions, asthma attacks, chronic inflammation, diseases, and infections. An abnormal basophil count, either high or low, might be a sign of an underlying health concern. High basophil count can correlate with hormone imbalances.

Basophils account for only around 1% of white blood cells, but play a role in allergy defense and stimulating antibodies against pathogens and parasitic organisms (ticks and worms) that cause injury/infection. If this percentage is high, that could be correlated with hormone imbalances, especially those related to the thyroid.

Eosinophils are a type of white blood cell that are part of the immune system and help protect the body from parasites, allergens, bacteria, and other organisms. Hormones, especially cortisol and estrogen, can impact eosinophils.

Eosinophils are a type of white blood cell that normally make up 1–4% of white blood cells, or less than 5% of total white blood cells. However, the percentage of eosinophils in your blood can range from 0–6% and get disrupted by hormonal imbalances.

Lymphocytes are immune cells that produce, store, and secrete hormones and hormone-like molecules that influence immune function. These cells also have receptors for hormones and signal transduction pathways.

A normal percentage of lymphocytes in human white blood cells is 20–40%. Lymphocytes are immune cells that produce, store, and secrete hormones and hormone-like molecules that influence immune function. These cells also have receptors for hormones and signal transduction pathways.

A red cell distribution width (RDW) test measures the variation in the size and volume of red blood cells (RBCs) in a blood sample. Elevated RDW levels are often associated with Hashimoto thyroiditis (HT), subclinical hypothyroidism, hyperthyroidism, and hypothyroidism - all of which are conditions related to thyroid hormones.

A normal percentage of monocytes in a healthy adult's white blood cell count is between 2% and 8%. Estrogen and other sex hormones can affect monocyte percentages, which may be related to hormone imbalances. 

Neutrophils are a type of white blood cell that are a key part of the immune system, helping the body fight infection. Neutrophil levels in the bloodstream increase as estrogen levels increase. Women also have higher neutrophil levels than men with higher androgen levels. During the menstrual cycle, neutrophil counts fluctuate and higher percentages are associated with higher serum estradiol levels. Estradiol and progesterone can also delay neutrophil apoptosis, which may contribute to the higher neutrophil counts in women. Progesterone can also delay neutrophil apoptosis, which may contribute to the higher neutrophil counts in women.

They are the most common type of granulocyte, making up 40–70% of all white blood cells in humans. Estrogen and progesterone imbalances are linked to changes in neurophil percentage.

A red blood cell (RBC) count measures the number of red blood cells, also known as erythrocytes, in your blood. Red blood cells carry oxygen from your lungs to every cell in your body. Your cells need oxygen to grow, reproduce, and stay healthy. Hormone imbalances can cause issues with red blood cells (RBCs) in a number of ways, including: anemia and Erythropoietin.

WBC stands for white blood cell, also known as leukocyte. White blood cells are a vital part of the body's immune system, helping to fight off infection, disease, and other foreign substances. Hormonal imbalances can directly affect white blood cell (WBC) counts. Both too much and too little thyroid hormone can reduce the number of WBCs produced. Glucocorticoids can also increase WBC production.

ALP is an enzyme found in many parts of your body. Each part of your body produces a different type of ALP. Most ALP is found in your liver, bones, kidneys, and digestive system, and tells us whether the liver and bones are healthy. ALP is affected by many hormones, including estrogen, insulin, and androgenic hormones.

ALT is an enzyme found mostly in the liver. When liver cells are damaged, they release ALT into the bloodstream. High levels of ALT in your blood may be a sign of a liver injury or disease. Alanine transaminase (ALT) levels in the blood can be affected by hormones, especially progesterone and estrogen.

AST (aspartate aminotransferase) is an enzyme that is found mostly in the liver, but it's also in muscles and other organs in your body. When cells that contain AST are damaged, they release the AST into your blood. AST levels can be affected by several hormones, especially thyroid hormones, sex hormones, and estrogens.

Albumin is a protein produced by the liver that's the most abundant protein in blood plasma. It has many functions, including: keeping fluid from leaking out of blood vessels, transporting hormones/vitamins/ enzymes, maintaining plasma oncotic pressure, and serving as a source for endogenous amino acids. When albumin is out-of-range, hormones and other important compounds aren't able to get to where they need to go in your body to fulfill their duties.

The albumin/globulin (A/G) ratio is a calculation that measures the relative proportion of albumin to globulin in the blood. Albumin is a water-soluble protein that transports substances in the blood, while globulins contribute to immune function and enzymatic activity. Since hormones are so closely linked to both albumin and globulin, an out-of-range A/G ratio could indicate hypoalbuminemia, kidney or liver disease, chronic infections, malnutrition, autoimmune diseases, certain cancers, type 2 diabetes, weakened immune system, dehydration, malnutrition, or gastrointestinal conditions.

A BUN test can reveal whether your urea nitrogen levels are higher than normal, suggesting that your kidneys may not be working properly. BUN levels can be affected by hormones, especially thyroid hormones and antidiuretic hormone (ADH). 

The blood urea nitrogen (BUN) to creatinine (BCR) ratio is a key indicator of kidney function. An out-of-range BCR could mean the kidneys aren't filtering and removing waste properly, which is important to know for overall health - including hormones since the kidneys produce several of them.

Calcium is one of the most important minerals in your body. About 1% of the calcium in your body is in your blood. The rest is stored in your bones and teeth. Having the right amount of calcium in your blood is necessary for your nerves, muscles, and heart to work properly. It also helps blood vessels move blood throughout your body and helps release hormones that affect many body functions.

Carbon dioxide is an odorless, colorless gas. It is a waste product that your body makes when it uses food for energy. Your blood carries carbon dioxide to your lungs. When you exhale, you breathe out carbon dioxide. Having too much or too little carbon dioxide in your blood can be a sign of a health problem. Most of the carbon dioxide in your body is in the form of bicarbonate, which is a type of electrolyte. Electrolytes are electrically charged minerals that help control the amount of fluid and the balance of acids and bases (pH balance) in your body. Hormone imbalances can cause carbon dioxide levels to go out-of-range.

Chloride is a type of electrolyte. Electrolytes are electrically charged minerals that help control the amount of fluids and the balance of acids and bases (pH balance) in your body. Hormone imbalances can cause chloride levels to go out-of-range.

A creatinine test is a measure of how well your kidneys are performing their job of filtering waste from your blood. Creatine can impact hormones in a number of ways, including by increasing anabolic hormones, which are associated with growth and tissue repair. 

Fasting glucose is often the first test used to screen for diabetes and prediabetes, and it therefore is a key measure of hormonal health - especially for conditions like PCOS that are closely linked to blood sugar regulation. Imbalances with insulin, estrogen, progesterone, and testosterone can all affect blood sugar levels.  

Globulin is a protein produced by the liver that has various functions in the body. The levels of different types of globulin can provide information about how well the immune system is working. Hormone imbalances can affect globulin levels.

Potassium is a mineral and electrolyte that helps with muscle and nerve communication, nutrient movement into cells, and waste removal from cells. It also helps maintain the body's water and electrolyte balance. In-range potassium levels are vital for hormone balance.

Sodium is an electrolyte and mineral that helps regulate fluid and acid-base balance, and is important for muscle and nerve function. Hormone imbalances can affect sodium levels in the body. The antidiuretic hormone (ADH), also known as vasopressin, is a hormone that regulates the body's water and salt balance. 

Bilirubin is a red-orange compound and yellowish substance that is produced when red blood cells break down as part of the body's normal process of clearing waste. Bilirubin levels can be affected by liver function, which can also impact hormone balance.

A total protein blood test measures the amount of protein in your blood, which can provide insight into your nutrition, liver and kidney health, and hormone regulation. Proteins are essential for overall health, as they serve as building blocks for many organs, hormones, and enzymes.

Estimated glomerular filtration rate (eGFR) is a blood test that measures how well your kidneys filter waste and toxins from your blood. Hormones, especially estrogen, progesterone, stress hormones, and thyroid hormones, can affect eGFR. 

Hematocrit, also known as HCT, is a blood test that measures the percentage of red blood cells in a person's blood by volume. Evidence suggests that androgen hormones, like testosterone, can increase hematocrit levels.

Hemoglobin (Hb) is a protein in red blood cells that carries oxygen from the lungs to the body's tissues and organs. Hemoglobin levels indicate the health of red blood cells and can help diagnose conditions like blood disorders and anemia. Anemia, and therefore hemoglobin, is strongly correlated with hormone imbalances.

MCH measures the average amount of hemoglobin in a person's red blood cells. Low levels of MCH can indicate iron-deficiency anemia while high levels of MCH can signal anemia caused by low levels of folic acid or vitamin B12. Anemia is strongly correlated with hormone imbalances.

MCHC is a blood test that measures the average amount of hemoglobin in a red blood cell (RBC) in relation to the cell's volume. High MCHC levels can be caused by a number of conditions, including some types of anemia, liver disease, and an overactive thyroid - therefore, linked to hormones. Low MCHC levels can be caused by iron deficiency anemia, thalassemia, or pancytopenia.

An MCV blood test measures the average size of your red blood cells. It is often used to assess potential anemia, which is strongly linked to hormones.

Platelets, also known as thrombocytes, are small, colorless, disc-shaped cell fragments found in blood and spleen that help form clots to stop or slow bleeding and aid in wound healing. Low estrogen levels can lead to decreased platelet counts and platelet activation. Age-related changes in platelet function are more pronounced in women than in men, possibly due to the influence of sex hormones. 

A monocyte is a type of immune cell that is made in the bone marrow and travels through the blood to tissues in the body where it becomes a macrophage or a dendritic cell. High monocyte levels, also known as monocytosis, can be a sign of: infection, autoimmune disease, blood disorder, cancer, and cardiovascular disease. Monocytosis can also be caused by stress or recovery from an infection. Low monocyte counts, also known as monocytopenia, can be caused by medical conditions that lower WBC count or disease treatments that suppress the immune system. Some causes include: Chemotherapy and radiation therapy, HIV and AIDS, Sepsis, not getting enough vitamins like B12/C/folate, and some medications like corticosteroids.
