Nutritional hypoproteinemia is due to severe limitation of protein intake in the diet. An example of nutritional hypoproteinemia is Kwashiorkor, a type of protein energy malnutrition affecting young children. Malabsorption, often caused by celiac disease or inflammatory bowel disease. Liver disease can also cause hypoproteinemia by decreasing ...
PSA is normally present in the blood at very low levels. The reference range of less than 4 ng/mL for the first commercial PSA test, the Hybritech Tandem-R PSA test released in February 1986, was based on a study that found 99% of 472 apparently healthy men had a total PSA level below 4 ng/mL. [37]
Once released, albumin distributes itself between the intravascular space (40%) in blood vessels, and extravascular spaces (60%) within the body's different tissues. In the blood plasma, albumin makes up 55 to 60% of total plasma protein by mass, with globulins making up a large part of the rest. In hypoalbuminemia, the amount of albumin in the ...
test for measuring the total amount of protein in serum. 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. While it is possible to analyze these proteins ...
For this reason, low ferritin levels carry more information than those in the normal range. A falsely low blood ferritin (equivalent to a false positive test) is very uncommon, [34] but can result from a hook effect of the measuring tools in extreme cases. [35] Low ferritin may also indicate hypothyroidism, [36] vitamin C deficiency or celiac ...
t. e. 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 ...
Hyponatremia. Hyponatremia or hyponatraemia is a low concentration of sodium in the blood. [4] It is generally defined as a sodium concentration of less than 135 mmol/L (135 mEq/L), with severe hyponatremia being below 120 mEq/L. [3][8] Symptoms can be absent, mild or severe. [2][9] Mild symptoms include a decreased ability to think, headaches ...
IgG deficiency is a form of dysgammaglobulinemia where the proportional levels of the IgG isotype are reduced relative to other immunoglobulin isotypes. IgG deficiency is often found in children as transient hypogammaglobulinemia of infancy, which may occur with or without additional decreases in IgA or IgM. IgG subclass deficiencies are also ...
