Overview
Laboratory findings consistent with the diagnosis of 11β-hydroxylase deficiency include elevated 17-hydroxyprogesterone, elevated androstenedione, elevated urinary 17-ketosteroids, and decreased renin.
Laboratory Findings
Laboratory findings consistent with the diagnosis of 11β-hydroxylase deficiency include:[1][2]
- Elevated serum levels of 11-deoxycorticosterone
- Elevated 17-hydroxyprogesterone
- Elevated androstenedione
- Elevated urinary 17-ketosteroids
- Elevated urinary tetra hydrometabolites
- Decreased cortisol
- Decreased aldosterone
- Decreased renin
- Hypokalemia
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.
