Free light chains (FLCs) are immunoglobulin light chains that are found in the serum (blood) in an unbound (free) state. In recent decades, measuring the amount of free light chains (FLCs) in the blood has become a practical clinical test. FLC tests can be used to diagnose and monitor diseases like multiple myeloma and amyloidosis.
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples.

The test, called PreTRM, tracks levels of two proteins in the blood that tend to rise during the second trimester in women who are at risk of delivering early. This patient’s test was negative.
Rare p phenotype (absence of P1PK antigens caused by null mutations in A4GALT): anti-P 1 (-), anti-P (-), anti-PP 1 P k (-), and anti-P k (-). These individuals have a very strong anti-PP 1 P k which can be associated with delayed hemolytic transfusion reactions and early spontaneous abortions or hemolytic disease of the fetus and newborn (HDFN).
A new approach to a routine blood test could predict a person’s 30-year risk of heart disease, research published Saturday in the New England Journal of Medicine found.. Doctors have long ...
