Overview

Laboratory findings consistent with the diagnosis of 21-hydroxylase deficiency differ in each disease sub-type. 17-hydroxyprogesterone level and cosyntropin stimulation test can be used for diagnosis.

Laboratory Findings

Laboratory findings consistent with the diagnosis of congenital adrenal hyperplasia due to 21-hydroxylase deficiency differ in each disease sub-type.^[1]^[2]

21-hydroxylase deficiency type	17-hydroxyprogesterone level	High dose Cosintropin stimulation test (250 mcg)
Classic salt-wasting	Greater than 3500 ng/dL	Not necessary
Classic non salt-wasting	Greater than 3500 ng/dL	Not necessary
Non-classic type	Children: greater than 82 ng/dL Adult females: greater than 200 ng/dL, morning serum sample during the follicular phase of the menstrual cycle	Necessary for confirmation

Salt-wasting crises in infancy in classic type

Low serum cortisol level
Hyponatremia, with a serum sodium typically between 105 mEq/L and 125 mEq/L
Hyperkalemia in these infants can be very high
Metabolic acidosis
Hypoglycemia

Genetic testing

Genetic testing can detect approximately 95 percent of mutations. Genetic testing should only be done if the laboratory tests are non diagnostic or for purposes of genetic counseling.

+===Salt-wasting crises in [[infancy]] in classic type===
+* Low [[serum]] [[cortisol]] level
+* [[Hyponatremia]], with a serum [[sodium]] typically between 105 mEq/L and 125 mEq/L
+* [[Hyperkalemia]] in these [[infants]] can be very high

-===Salt-wasting crises in infancy===
+=== Genetic testing ===
-* Basic chemistries will reveal [[hyponatremia]], with a serum Na<sup>+</sup> typically between 105 and 125 mEq/L. [[Hyperkalemia]] in these infants can be extreme&mdash;levels of K<sup>+</sup> above 10 mEq/L are not unusual&mdash;as can the degree of [[metabolic acidosis]]. [[Hypoglycemia]] may be present. This is termed a salt-wasting crisis and rapidly causes death if not treated.
+[[Genetic testing]] can detect approximately 95 percent of [[mutations]]. [[Genetic testing]] should only be done if the laboratory tests are non diagnostic or for purposes of [[genetic counseling]].
-===Childhood onset (simple virilizing) CAH===
-A diagnosis of SVCAH is usually confirmed by discovering extreme elevations of [[17-hydroxyprogesterone]] along with moderately high testosterone levels. A [[ACTH|cosyntropin]] stimulation test may be needed in mild cases, but usually the random levels of 17OHP are high enough to confirm the diagnosis.
-===Late onset (nonclassical) CAH===
-Diagnosis of late-onset CAH may be suspected from a high 17-hydroxyprogesterone level, but some cases are so mild that the elevation is only demonstrable after cosyntropin stimulation.
