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 ...
11-Deoxycortisol in mammals has limited glucocorticoid activity, but it is the direct precursor of the major mammalian glucocorticoid, cortisol. [15] As a result, the level of 11-deoxycortisol is measured to diagnose impaired cortisol synthesis, to find out the enzyme deficiency that causes impairment along the pathway to cortisol, and to differentiate adrenal disorders.

Cortisol levels are lower in CAH subjects, on average, [38] however, in milder cases cortisol levels can be normal, but, this has not been yet well studied. Cortisol measurement using immunoassays is prone to cross-reactivity with various substances including 21-deoxycortisol that raises due to 21-hydroxylase deficiency, leading to falsely high ...
An individual may have normal total cortisol but have a lower than normal level during a certain period of the day and a higher than normal level during a different period. Therefore, some scholars question the clinical utility of cortisol measurement. [70] [71] [72] [73]
"Your blood pressure is supposed to be under 140 over 90, optimally closer to 120 over 80."
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.
The long test uses 1 mg tetracosactide (intramuscular). Blood is taken 1, 4, 8, and 24 hours later. Normal plasma cortisol level should reach 1,000 nmol/L by 4 hours. In primary Addison's disease, the cortisol level is reduced at all stages, whereas in secondary corticoadrenal insufficiency, a delayed but normal response is seen.
