TSH (THYROID STIMULATING HORMONE) IS A HORMONE PRODUCED BY THE PITUITARY GLAND THAT REGULATES THYROID FUNCTION. IT STIMULATES THE THYROID GLAND TO PRODUCE THYROID HORMONES, WHICH CONTROL METABOLISM, BODY TEMPERATURE, AND HEART RATE. ABNORMAL TSH LEVELS CAN INDICATE THYROID DISORDERS SUCH AS HYPERTHYROIDISM (OVERACTIVE THYROID) OR HYPOTHYROIDISM (UNDERACTIVE THYROID). BY MEASURING TSH, HEALTHCARE PROVIDERS CAN DIAGNOSE AND MONITOR THYROID CONDITIONS.

THIS TEST MEASURES THE LEVEL OF IGM ANTIBODIES IN YOUR BLOOD THAT TARGET PHOSPHOLIPIDS, A TYPE OF FAT MOLECULE. THESE ANTIBODIES CAN INTERFERE WITH BLOOD CLOTTING, POTENTIALLY LEADING TO COMPLICATIONS LIKE BLOOD CLOTS, MISCARRIAGES, OR STROKES. HIGH LEVELS OF IGM PHOSPHOLIPID ANTIBODIES MAY INDICATE AN AUTOIMMUNE DISORDER CALLED ANTIPHOSPHOLIPID SYNDROME (APS).

An anti-nuclear antibody (ANA) profile is a blood test that detects antibodies produced by the immune system that mistakenly target the bodys own cell nuclei.Elevated ANA levels can indicate the presence of an autoimmune disease, such as systemic lupus erythematosus (SLE), rheumatoid arthritis, or Sjogrens syndrome. The test measures both the presence and pattern of ANA, with different patterns associated with specific autoimmune conditions. A positive ANA test often requires further evaluation to confirm a diagnosis.

CARDIOLIPIN ANTIBODIES ARE USEFUL IN IDENTIFYING PATIENTS WITH AN INCREASED RISK OF THROMBOSIS, RECURRENT SPONTANEOUS ABORTIONS AND PHOSPHOLIPID ANTIBODY SYNDROME. CARDIOLIPIN ANTIBODY MAY BE ELEVATED IN PATIENTS WITH SLE AND RELATED AUTOIMMUNE DISORDERS.

CARDIOLIPIN ANTIBODIES ARE USEFUL IN IDENTIFYING PATIENTS WITH AN INCREASED RISK OF THROMBOSIS, RECURRENT SPONTANEOUS ABORTIONS AND PHOSPHOLIPID ANTIBODY SYNDROME. CARDIOLIPIN ANTIBODY IGG IS THE MOST SENSITIVE BUT THE LEAST SPECIFIC ANTIBODY.

CARDIOLIPIN ANTIBODIES ARE USEFUL IN IDENTIFYING PATIENTS WITH AN INCREASED RISK OF THROMBOSIS, RECURRENT SPONTANEOUS ABORTIONS AND PHOSPHOLIPID ANTIBODY SYNDROME. CARDIOLIPIN ANTIBODY IGM IS LESS SENSITIVE BUT MORE SPECIFIC THAN CARDIOLIPIN ANTIBODY IGG.

TESTING FOR PHOSPHOLIPID ANTIBODIES IS INDICATED IN CASES OF UNEXPLAINED ARTERIAL / VENOUS THROMBOSIS, PREGNANCY WITH UNEXPLAINED FETAL DEATHS, SPONTANEOUS ABORTIONS, PRESENCE OF UNEXPLAINED CUTANEOUS CIRCULATORY DISTURBANCE LIKE LIVIDO RETICULARIS AND PRESENCE OF SYSTEMIC RHEUMATIC DISEASE LIKE LE. THIS TEST IS ALSO USED IN CASES OF UNEXPLAINED THROMBOCYTOPENIA, HEMOLYTIC ANEMIA & NON-BACTERIAL THROMBOTIC ENDOCARDITIS.

The Lupus Anticoagulant by dRVVT (dilute Russell's viper venom time) test is a coagulation assay used to detect the presence of lupus anticoagulants (LA), which are a type of antiphospholipid antibodies. Despite their name, these antibodies are not typically associated with bleeding disorders or systemic lupus erythematosus and are in fact linked to an increased risk of blood clots (thrombosis). The dRVVT test works by using a diluted venom that directly activates Factor X of the coagulation cascade. A prolonged clotting time in the initial screening phase suggests the presence of an inhibitor. This is followed by a confirmatory test using an excess of phospholipids. If the prolonged clotting time corrects (shortens) in the confirmatory step, it indicates that the inhibitor is phospholipid-dependent, which is a characteristic of lupus anticoagulants.
