ACETYL-CHOLINE-RECEPTOR-ANTIBODIES (AChR Antibodies) Acetyl Choline Receptor Antibodies (AChR antibodies) are autoantibodies produced by the immune system that mistakenly attack acetylcholine receptors present at the neuromuscular junction. These receptors play a crucial role in transmitting nerve signals to muscles,...

What is ACA-IgM? ACA-IgM, also known as Anti-Cardiolipin Antibody IgM, is a blood test used to detect IgM antibodies directed against cardiolipin, a type of phospholipid found in cell membranes. The presence of these antibodies may indicate autoimmune activity in the body, particularly related to antiphospholipid...

ACA-IgA (Anti-Centromere Antibody Immunoglobulin A) is a specialized autoimmune blood test used to detect antibodies that target centromere proteins within the nucleus of cells. The presence of ACA-IgA is commonly associated with certain autoimmune connective tissue disorders, particularly limited cutaneous systemic...

The Absolute Lymphocyte Count (ALC) is an important blood test parameter that measures the exact number of lymphocytes present in the blood. Lymphocytes are a type of white blood cell (WBC) that play a crucial role in the body’s immune defense system. The ALC test helps doctors assess immune function, detect infections,...

The ABPA Panel is a specialized diagnostic blood test used to identify Allergic Bronchopulmonary Aspergillosis (ABPA), a hypersensitivity lung disorder caused by an exaggerated immune response to Aspergillus species, commonly Aspergillus fumigatus. This condition is most often seen in patients with asthma or cystic...

The 24-Hrs Urine Uric Acid test is a diagnostic laboratory investigation used to measure the amount of uric acid excreted in urine over a full 24-hour period. Uric acid is a waste product formed from the breakdown of purines, substances commonly found in certain foods and body tissues. This test plays a crucial role in...

The 24-Hrs Urine Protein test is a diagnostic laboratory investigation used to measure the total amount of protein excreted in urine over a 24-hour period. This test plays a crucial role in evaluating kidney function and identifying abnormal protein loss, which may indicate underlying kidney disease or systemic health...

Why is the 24-Hrs Urine Metanephrine Test Done? Doctors commonly recommend the 24-hour urine metanephrine test when symptoms suggest excessive production of adrenal hormones. It is primarily used to help diagnose or rule out conditions such as pheochromocytoma and paraganglioma—tumors that can cause abnormal hormone...

24-Hrs Urine Creatinine is a laboratory test that measures the total amount of creatinine excreted in urine over a 24-hour period. Creatinine is a waste product formed from normal muscle metabolism and is filtered out of the blood by the kidneys. This test plays a crucial role in evaluating kidney function, muscle mass,...
