The most abundant mineral in the body, essential for bone health, muscle contraction, nerve function, and blood clotting. Blood calcium is tightly regulated by parathyroid hormone and vitamin D. Abnormal levels can indicate parathyroid disorders.

The primary stress hormone, produced by the adrenal glands. Cortisol regulates metabolism, immune response, blood pressure, and the sleep-wake cycle. Chronically elevated cortisol from stress contributes to weight gain, immune suppression, and metabolic dysfunction.

An enzyme found primarily in muscle tissue (skeletal and cardiac). Elevated CK indicates muscle damage from exercise, injury, or disease. Very high levels can indicate rhabdomyolysis, a potentially dangerous breakdown of muscle tissue.

Precursor to other hormones

The primary iron storage protein. Ferritin reflects total body iron stores and is the first marker to drop in iron deficiency. However, ferritin also rises with inflammation, infection, and liver disease, which can mask true iron deficiency.

Essential for DNA synthesis, cell division, and red blood cell formation. Folate deficiency causes megaloblastic anemia and, during pregnancy, increases the risk of neural tube defects. Works closely with vitamin B12.

A calculated ratio of total testosterone to SHBG that estimates the amount of biologically active testosterone. FAI is particularly useful in women for assessing androgen excess in conditions like PCOS.

Reflects your average blood sugar over the past 2–3 months by measuring the percentage of hemoglobin with attached glucose. HbA1c is the gold standard for diagnosing and monitoring diabetes, unaffected by daily fluctuations.

A mineral essential for oxygen transport (in hemoglobin), energy production, and immune function. Serum iron measures the amount circulating in blood, but ferritin and TIBC provide a more complete picture of iron status.

Works with FSH to regulate reproductive function. In women, an LH surge triggers ovulation. In men, LH stimulates testosterone production. Abnormal levels can indicate pituitary or gonadal disorders.

Myoglobin is a protein in heart and skeletal muscles. Elevated levels indicate muscle injury, including potential heart attack.

A mineral essential for bone formation, energy metabolism (ATP), and acid-base balance. Phosphate levels are inversely related to calcium and regulated by parathyroid hormone and vitamin D.

A protein that binds and transports sex hormones (testosterone, estrogen) in the blood. High SHBG reduces the amount of free, active hormones available. SHBG increases with age, thyroid hormones, and estrogen; decreases with obesity and insulin resistance.

The primary male sex hormone, also important in women at lower levels. Testosterone regulates muscle mass, bone density, fat distribution, libido, and mood. Levels decline naturally with age in both sexes.

A waste product from the breakdown of purines (found in certain foods and body cells). High levels can form crystals in joints (gout) or kidneys (kidney stones). Also associated with cardiovascular disease and metabolic syndrome.

Essential for nerve function, DNA synthesis, and red blood cell formation. B12 deficiency can cause anemia, neuropathy, fatigue, and cognitive impairment. Common in vegans, vegetarians, older adults, and those taking metformin or acid-reducing medications.

The best indicator of overall vitamin D status. Vitamin D is essential for calcium absorption, bone health, immune function, and mood regulation. Deficiency is extremely common, especially in northern latitudes, and linked to increased disease risk.
