Serum protein electrophoresis (SPEP or SPE) is a laboratory test that examines specific proteins in the blood called globulins. [1] The most common indications for a serum protein electrophoresis test are to diagnose or monitor multiple myeloma , a monoclonal gammopathy of uncertain significance (MGUS), or further investigate a discrepancy ...
Hypergammaglobulinemia is a condition that is characterized by the increased levels of a certain immunoglobulin in the blood serum. [1] The name of the disorder refers to an excess of proteins after serum protein electrophoresis (found in the gammaglobulin region). [citation needed]
To see any decrease or increase in the levels of globulin fraction it should be done in the serum electrophoresis and be checked for any certain abnormalities. [5] Globulins are usually tested through a blood test to see how much protein is in a patient's blood. The blood proteins that should be seen would be globulins and albumin.
Serum total protein, also known as total protein, is a clinical chemistry parameter representing the concentration of protein in serum. [1] Serum contains many proteins including serum albumin, a variety of globulins, and many others.
The direct Coombs test is used to detect antibodies or complement proteins attached to the surface of red blood cells. To perform the test, a blood sample is taken and the red blood cells are washed (removing the patient's plasma and unbound antibodies from the red blood cells) and then incubated with anti-human globulin ("Coombs reagent").
A macroglobulin is a plasma globulin of high molecular weight. [1] Elevated levels of macroglobulins (macroglobulinemia) may cause manifestations of excess blood viscosity (as is the case for IgM antibodies in Waldenström macroglobulinemia) and/or precipitate within blood vessels when temperature drops (as in cryoglobulinaemia).
Acid–base and blood gases are among the few blood constituents that exhibit substantial difference between arterial and venous values. [6] Still, pH, bicarbonate and base excess show a high level of inter-method reliability between arterial and venous tests, so arterial and venous values are roughly equivalent for these. [44]
α 2-Macroglobulin levels are increased when the serum albumin levels are low, [18] which is most commonly seen in nephrotic syndrome, a condition wherein the kidneys start to leak out some of the smaller blood proteins. Because of its size, α 2-macroglobulin is retained in the bloodstream.
