My doc says that GH should be tested with a IGF-1 test. Is this wrong?
And why would I have to take a massive 10iu dose to test GH?
Smokescreen, your doc is correct that it should be an IGF-1 test and you can find some of the numbers for your age group below:
he following table shows typical IGF-1 (somatomedin -c) values for a given age. IGF-1 (Insulin like Growth Factor 1) levels are typically used to indicate the availability of growth hormone in the human body.
This table shows specific values from a specific laboratory. Due to different calibration used by the different laboratories, the IGF-1 reference values per age may differ considerably per laboratory.
Females/Males (Age) Range (ng/mL)
1-5 years 50-327
6-10 years 52-452
11-15 years 111-996 (1)
16-20 years 127-903 (1)
21-25 years 116-358
26-30 years 117-329
31-35 years 115-307
36-40 years 109-284
41-45 years 101-267
46-50 years 94-252
51-55 years 87-238
56-60 years 81-225
61-65 years 75-212
66-70 years 69-200
71-75 years 64-188
76-80 years 59-177
81-85 years 55-166
(1) Highest values at the ages of 15-16 years.
As an example lets view the values for a person in the 46 to 50 year range. The notation for the values is 94(low)-252(high). In this case we will simplify the calculation of the median as (low + high)/2, in this case (94(low) + 252(high)) = 346, 346/2 = 173.
When evaluating test results always keep the following in mind:
Always use the same laboratory and the same type of IGF-1 test. Due to calibration or differences in IGF-1 testing methods, considerable differences may result when intermixing laboratories and testing methods.
Ask for IGF-1 reference values per age for your type of test from your laboratory or testing entity.
Always test yourself before starting any form of HgH human growth hormone supplementation. You need a reference (starting) point to be able to see the impact of the HgH treatment in relation to no growth hormone treatment.
Malnutrition will cause low somatomedin-c (IGF-1) values in spite of normal amounts of circulating HgH human growth hormone.
If you think you have an extremely low or high hgh human growth hormone level consult a physician or an endocrinologist.
If your level is below the median and you experience HgH insufficiency symptoms you should definitely consider HgH supplementation.
Before administering any form of HgH human growth hormone to youths and children (anyone under 20 years of age) consult a physician or an endocrinologist. In our opinion you should not give youths or children HgH human growth hormone supplementation unless there is a medical condition that requires it, and proper medical monitoring is available.
I am assuming that the 10IUs (which is normally one vile of HGH) is used to see the spike in your HGH and IGF levels. Granted IGF testing is not an exact science, but it is one way to test credibility.
