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.
This can cause false results in assays such as coagulation assays (causing falsely increased clotting times) or blood cell differentials (causing a false increase in poikilocytes, particularly burr cells.) In either case, the most common and feasible way to correct the problem is to simply recollect the specimen.
Positive Bowditch effect causes an increase in cardiac output due to the increased force of contraction of heart muscles. [7]This phenomenon is usually absent or even reversed (negative Bowditch effect) in heart failure and other diseases of heart, such as cardiomyopathy and coronary artery disease.
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. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
The two heavy chains are colored red and blue and the two light chains green and yellow. [1] The immunoglobulin heavy chain (IgH) is the large polypeptide subunit of an antibody (immunoglobulin). In human genome, the IgH gene loci are on chromosome 14. A typical antibody is composed of two immunoglobulin (Ig) heavy chains and two Ig light chains.
The formation of a bicarbonate ion will release a proton into the plasma, decreasing pH (increased acidity), which also shifts the curve to the right as discussed above; low CO 2 levels in the blood stream results in a high pH, and thus provides more optimal binding conditions for hemoglobin and O 2. This is a physiologically favored mechanism ...
A blood gas test or blood gas analysis tests blood to measure blood gas tension values and blood pH.It also measures the level and base excess of bicarbonate.The source of the blood is reflected in the name of each test; arterial blood gases come from arteries, venous blood gases come from veins and capillary blood gases come from capillaries.

A newly developed diagnostic test, called Immunochromatography (IC) Strip Tests, uses monoclonal antibodies to detect Hemoglobin Barts in red blood cells' lysate. This diagnostic test is validated for positive and negative predictive values. It is also cheap and easy, making regular screening for alpha-thalassemia a plausible possibility. [9] [10]
