And I never heard of that test. The test used is a bloodwork measuring igf-1 levels. If they're under 300 they often have
Many things can cause igf-1 levels to drop.This determines if you have a real problem with pituitary gland and need HGH therapy.
They use a drip of
Arginine Hydrochloride which is how they usually diagnose such conditions as panhypopituitarism, pituitary dwarfism, chromophobe adenoma, postsurgical craniopharyngioma, hypophysectomy, pituitary trauma, acromegaly, gigantism and problems of growth and stature.
Test Procedure
The intravenous infusion of R-Gene® 10 is a part of the test for measurement of pituitary reserve of human growth hormone and, for successful administration of the test, clinical conditions and procedures should be as follows:
1.The test should be scheduled in the morning following a normal night's sleep, and an overnight fast should continue through the test period.
2.Patients must be placed at bed rest for at least 30 minutes before the infusion begins. Care should be taken to minimize apprehension and distress. This is particularly important in children.
3.R-Gene® 10 (Arginine Hydrochloride Injection, USP) is a hypertonic solution and should only be infused through an indwelling needle or soft catheter placed in an antecubital vein or other suitable vein (See PRECAUTIONS). Blood samples should be taken by venipuncture from the contra-lateral arm.
4.A desirable schedule for drawing blood samples is at -30, 0, 30, 60, 90, 120 and 150 minutes.
5.R-Gene® 10 should be infused beginning at zero time at a uniform rate which will permit the recommended dose to be administered over 30 minutes.
6.Blood samples should be promptly centrifuged and the plasma stored at -20°C until assayed by one of the published radioimmunoassay procedures.
7.Diagnostic test results showing a deficiency of pituitary reserve for HGH should be confirmed by a second test with R-Gene® 10, or
one may elect to confirm with the insulin hypoglycemia test. A waiting period of one day is advised between tests.
