Albumin is an acute negative phase respondent and not a reliable indicator of nutrition status. [10] Low albumin levels can also indicate chronic malnutrition from protein losing enteropathy. [3] This is often caused or exacerbated by ulcerative colitis, [11] but can also be seen in cardiac disease and systemic lupus erythematosus. [3]
There is a certain equation to figure out the value of globulin. The equation goes by this Globulins = Total protein - Albumin since it should not have an albumin protein within the globulin. Usually, the concentration of globulin is measured either in grams per liter or milligrams per deciliter.
The serum-ascites albumin gradient or gap (SAAG) is a calculation used in medicine to help determine the cause of ascites. [1] The SAAG may be a better discriminant than the older method of classifying ascites fluid as a transudate versus exudate. [2] The formula is as follows: SAAG = (serum albumin) − (albumin level of ascitic fluid).
Serum contains many proteins including serum albumin, a variety of globulins, and many others. While it is possible to analyze these proteins individually, total protein is a relatively quick and inexpensive analysis that does not discriminate by protein type.
CSF/serum albumin ratio is a test performed to compare the levels of albumin in the cerebrospinal fluid and the serum. It is useful as a measure of the integrity of the blood–brain barrier . [ 1 ] [ 2 ] [ 3 ]
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 between a low albumin and a relatively high total protein.
Albumin is a family of globular proteins, the most common of which are the serum albumins. All of the proteins of the albumin family are water- soluble , moderately soluble in concentrated salt solutions, and experience heat denaturation .
Hypoproteinemia is a condition where there is an abnormally low level of protein in the blood. There are several causes that all result in edema once serum protein levels fall below a certain threshold.
