Used in the differential diagnosis of isolated symptoms suggestive of carcinoid syndrome, in particular flushing (5-HIAA or serum chromogranin A measurements are first-line tests). Also useful as a second-order test in the follow-up of patients with known or treated carcinoid umors in serum specimens.

A screening for the presence or absence of hemoglobin S. Heterozygous hemoglobin S is the most common form of hemoglobinopathy in the US. It detects only the presence of Hb S and cannot differentiate the sickle-cell trait from sickle-cell disease.
Useful when monitoring whole blood sirolimus concentration during therapy, particularly in individuals coadministered CYP3A4 substrates, inhibitors, or inducers. Also useful for adjusting dose to optimize immunosuppression while minimizing toxicity, and for evaluating patient compliance.
Useful for evaluating patients with signs and symptoms of a connective tissue disease in whom the test for antinuclear antibodies is positive, especially those with signs and symptoms consistent with Sjogren syndrome or lupus erythematosus. Not useful in patients without demonstrable antinuclear antibodies.

Useful when evaluating a patient for autoimmune hepatitis. Usually ordered when a person presents with symptoms such as fatigue and jaundice along with abnormal findings on routine liver tests such as aspartate aminotransferase (AST) and/or bilirubin. These autoantibody tests may be ordered along with other testing when a healthcare practitioner is investigating liver disease and wants to distinguish between different causes of liver injury, including viral infections, drugs, alcohol abuse, toxins, genetic conditions, metabolic conditions, and autoimmune disorders.

A test that detects and identifies bacteria that cause infections of the lower digestive tract. Distinguishes between the types of bacteria that cause disease (pathogenic) and the types that are normally found in the digestive tract (normal flora).
Useful for conditions associated with increased fecal leukocytes including antibiotic-associated colitis, ulcerative colitis, shigellosis, salmonellosis, Campylobacter, Yersinia, and amoebiasis.
Useful for qualitative detection of IgG and IgM antibodies directed against Treponema pallidum (TP) in human serum or plasma. It is intended to be used as an initial diagnostic testor or in conjunction with a nontreponemal laboratory test and clinical findings to aid in the diagnosis of syphilis infection.
