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 ...
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 90 percent reference interval for serum glucose of 26 to 181 mg/dL has been reported for captured mountain goats (Oreamnos americanus), where no effects of the pursuit and capture on measured levels were evident. [17] For beluga whales, the 25–75 percent range for serum glucose has been estimated to be 94 to 115 mg/dL. [18]
Glucose testing can be used to diagnose or indicate certain medical conditions. [citation needed]High blood sugar may indicate . gestational diabetes.This temporary form of diabetes appears during pregnancy, and with glucose-controlling medication or insulin symptoms can be improved.
Genetic variants in the CYP21A2 gene cause a disturbance in the development of the enzyme, leading to congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency. Gene conversion events involving the functional gene and the pseudogene account for many cases of steroid 21-hydroxylase deficiency. [64] CAH is an autosomal recessive ...

[2] [3] Congenital adrenal hyperplasia due to 21-hydroxylase deficiency in all its forms accounts for over 95% of diagnosed cases of all types of congenital adrenal hyperplasia. [4] Unless another specific enzyme is mentioned, CAH in most contexts refers to 21-hydroxylase deficiency, and different mutations related to enzyme impairment have ...
The insulin index compares foods in amounts with equal overall caloric content (240 kcal or 1000 kJ). Insulin indexes are scaled relative to white bread, while glycemic index scores nowadays are usually scaled with respect to pure glucose, although in the past white bread has been a reference point for GI measurements as well.
