80828-7 Pepsin A+Pepsinogen A [Mass/volume] in Lower respiratory specimen by Immunoassay

Term Description

The presence of gastric pepsin A in a patient's airway is a marker for aspiration and assists in the diagnosis of gastroesophageal reflux. Chronic aspiration of gastric contents may worsen lung disease in premature infants, or other mechanically ventilated patients. PMID: 16954956 This assay detects both pepsin A and pepsinogen A and does not differentiate between the two. A level of less than 3 is considered in range. (One unit of pepsin A=0.1ng/ml pepsin A is a measure of concentration (ng/ml) expressed in an arbitrarily defined unit.)

LP206550-8   Pepsin A+Pepsinogen A
Pepsin is the principal proteolytic enzyme of vertebrate gastric juice. Pepsin's inactive precursor form, pepsinogen, is produced in stomach mucosa. The minor pepsins are designated "B", "C", and "D". "A" is the major component. Source: Regenstrief LOINC, Pepsin

80832-9 Protein [Mass/volume] in Lower respiratory specimen

Part Descriptions

LP15838-3   Protein
Protein testing is performed to evaluate and monitor liver and kidney function and to detect and diagnose early kidney damage and various other diseases. Elevated protein levels may also be due to an infection, medication, vigorous exercise, or emotional or physical stress. Body fluids contain many different proteins that serve diverse functions such as transport of nutrients, removal of toxins, control of metabolic processes, and defense against invaders. Testing for protein levels may be done as part of a routine physical, a pregnancy workup, in cased of a suspected UTI, as part of a hospital admission, or to evaluate kidney function.

80830-3 pH of Lower respiratory specimen

Part Descriptions

LP14752-7   pH
pH is a measure of the acidity or basicity of a solution. It is defined as the cologarithm of dissolved hydrogen ions (H+). Hydrogen ion activity coefficients cannot be measured experimentally, so they are based on theoretical calculations. The pH scale is not an absolute one, it is relative to a set of internationally established standard solutions. pH 7.0 is considered neutral.

LP14752-7   pH
Potentia Hydrogenii, commonly known as pH, is a quantitative measurement of the acidity or basicity of a substance. A substance's pH value is based on a relative scale from 1-14 depending on the substance's proton ion concentration (H+). A higher proton ion concentration results in a lower pH value. Therefore, a pH value between 0 and 7 is an acidic substance whereas a pH value between 7 and 14 is an alkaline/basic substance. A pH value of exactly 7 is a neutral substance. [https://labtestsonline.org/understanding/analytes/SearchForm?Search=pH&action_ProcessSphinxSearchForm=Go] The specific pH value of the blood is crucial in maintaining bodily functions. When the blood pH value is below normal range it is called acidosis. When the blood pH value is above normal range, it is called alkadosis. Acidosis/alkadosis can be divided into two categories: metabolic and respiratory. [https://labtestsonline.org/understanding/analytes/blood-gases/tab/test/] Source: Regenstrief LOINC
