FTA-ABS stands for fluorescent treponemal antibody absorbed, a blood serum screening test for syphilis designed to demonstrate the presence or absence of specific antibodies directed against the organism (Treponema pallidum) responsible for syphilis.
FTA-ABS detects the majority but not all cases of the disease. It is thus a way of screening for the disease.
A negative FTA-ABS test result is consistent with a person not having syphilis. However, a person may have a negative FTA-ABS test result while in the early (primary) and late (tertiary) stages of the disease. In the middle (secondary) stage of syphilis, the FTA-ABS test is most reliable and is reportedly positive in 100% of cases.

- Test, NSE
neuroblastoma, small cell lung cancer, medullary thyroid cancer, carcinoid tumors, endocrine tumors of the pancreas, and melanoma. Studies of NSE as a tumor marker have concentrated primarily on patients with neuroblastoma and small cell lung cancer. Measurement of NSE levels in patients with these two diseases can provide information about the extent of the disease […]
