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 ...
Blood should be taken soon after a bout of pancreatitis pain, otherwise it is excreted rapidly by the kidneys. Salivary α-amylase has been used as a biomarker for stress [10] [11] and as a surrogate marker of sympathetic nervous system (SNS) activity [12] that does not require a blood draw.
Blood serum amylase may be measured for purposes of medical diagnosis. A higher than normal concentration may reflect any of several medical conditions, including acute inflammation of the pancreas (which may be measured concurrently with the more specific lipase ), [ 12 ] perforated peptic ulcer , torsion of an ovarian cyst , strangulation ...
The standard definition of a reference range for a particular measurement is defined as the interval between which 95% of values of a reference population fall into, in such a way that 2.5% of the time a value will be less than the lower limit of this interval, and 2.5% of the time it will be larger than the upper limit of this interval, whatever the distribution of these values.
A basic metabolic panel (BMP) is a blood test consisting of a set of seven or eight biochemical tests and is one of the most common lab tests ordered by health care providers.
The reference range for total protein is typically 60-80g/L. (It is also sometimes reported as "6.0-8.0g/dl"), [ 2 ] but this may vary depending on the method of analysis. Concentrations below the reference range usually reflect low albumin concentration, for instance in liver disease or acute infection .
Alpha-amylase 1 is an enzyme that in humans is encoded by the AMY1A gene. [3] This gene is found in many organisms. Amylases are secreted proteins that hydrolyze 1,4-alpha-glucoside bonds in oligosaccharides and polysaccharides, and thus catalyze the first step in digestion of dietary starch and g
A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a hypodermic needle, or via fingerprick. Multiple tests for specific blood components, such as a glucose test or a cholesterol test , are often grouped together into one test panel called a blood panel or blood work .
