This handout explains several blood tests often used when doctors are checking for autoimmune or inflammatory conditions, such as rheumatoid arthritis (RA) and lupus. It covers what each test looks for, why it may be ordered, and how results are usually used. These tests support the diagnosis but are not the whole story—symptoms, exam, and sometimes imaging are also important.
Abnormal testosterone levels can cause fatigue, weight gain, low libido, mood swings, or irregular periods.
Elevated testosterone may signal PCOS or other hormonal disorders.
Testosterone helps maintain muscle strength and bone density, especially with aging.
Ideal for women undergoing HRT or other treatments that affect hormone levels.
Women experiencing fatigue, weight gain, low sex drive, or hair thinning.
Those diagnosed with or at risk for PCOS (Polycystic Ovary Syndrome).
Individuals tracking hormonal balance through different life stages (perimenopause, menopause).
Women on hormone therapy, fertility treatments, or certain medications affecting hormone levels.
Measures antibodies linked to rheumatoid arthritis. Important for women to help diagnose autoimmune joint disease early, allowing for timely treatment to reduce pain and prevent joint damage.
Detects antibodies often present in rheumatoid arthritis. Important for women to identify early autoimmune joint disease and guide timely treatment to prevent long-term damage.
Screens for antinuclear antibodies and, if positive, tests for 11 specific antibodies. Important for women to detect autoimmune diseases like lupus, Sjögren’s, or scleroderma, which are more common in women and can affect multiple organs.
Measures high-sensitivity C-reactive protein, a marker of inflammation linked to heart disease risk. Important for women to identify early cardiovascular risk, especially when combined with other heart health tests, and to monitor the impact of lifestyle or treatment changes.
Measures how quickly red blood cells settle in a test tube, which can indicate inflammation in the body. Important for women to help detect and monitor inflammatory or autoimmune conditions that may affect joints, muscles, or overall health.
