Pediatric: < or = 5 days: < or = 50 ng/mL; 5 days - < 3 months: < or = 10 ng/mL; 3 months - < 2 years: < or = 1.2 ng/mL; 2 years - puberty onset: < or = 1.2 ng/mL; Tanner II - IV: < or = 1.2 ng/mL; Adults: Males: < or = 0.5 ng/mL; Premenopausal females: < or = 1.2 ng/mL; Postmenopausal females: < or = 1.8 ng/mL.
Test Usage:
Quantitating the alpha-subunit has been advocated as a monitoring test to detect the recurrence of tumors in patients who have undergone resection of pituitary adenomas.
Test Methodology:
Immunochemiluminescent Assay (ICMA)
Additional Information:
The alpha-subunit of pituitary glycoprotein hormones assay has been called the alpha-human chorionic gonadotropin (hCG) assay. However, the assay measures the alpha-subunit of thyroid-stimulating hormone and other pituitary glycoproteins, in addition to that of hCG. Test sent to Mayo Medical Laboratories.
