Antinuclear antibodies are associated with rheumatic diseases including Systemic Lupus Erythematous (SLE), mixed connective tissue disease, Sjogren's syndrome, scleroderma, polymyositis, CREST syndrome, and neurologic SLE. Reflex and Titer tests may incur additional charges when results require additional tests to be performed.
C-Reactive Protein Cardiac (hs CRP) Useful in predicting risk for cardiovascular disease.
Bacterial sepsis constitutes one of the most serious infectious diseases. The detection of microorganisms in a patient's blood has importance in the diagnosis and prognosis of endocarditis, septicemia, or chronic bacteremia.
Aerobic culture, anaerobic culture. If culture is positive, identification will be performed at an additional charge (CPT code(s): 87076 or 87106 or 87077 or 87140 or 87143 or 87147 or 87149).
Antibiotic susceptibilities are only performed when appropriate (CPT code(s): 87181 or 87184 or 87185 or 87186).
To screen for and monitor kidney dysfunction in those with known or suspected kidney disease. Cystatin C is a relatively small protein that is produced throughout the body by all cells that contain a nucleus and is found in a variety of body fluids, including the blood. It is produced, filtered from the blood by the kidneys, and broken down at a constant rate. This test measures the amount of cystatin C in blood to help evaluate kidney function.Cystatin C is filtered out of the blood by the glomeruli, clusters of tiny blood vessels in the kidneys that allow water, dissolved substances, and wastes to pass through their walls while retaining blood cells and larger proteins. What passes through the walls of the glomeruli forms a filtrate fluid. From this fluid, the kidneys reabsorb cystatin C, glucose, and other substances. The remaining fluid and wastes are carried to the bladder and excreted as urine. The reabsorbed cystatin C is then broken down and is not returned to the blood.
