Ranges
Each lab publishes a reference range for the population groups it tests, usually the middle 95% of results. These intervals describe that population, not an optimal or healthy target. How ranges differ
Quest Diagnostics, Growth Hormone (GH) 521
| Population | Interval |
|---|---|
| Adult | ≤7.1 ng/mL |
| Children (<20 years) | ≤10.1 ng/mL |
Tests
Check the catalog code, specimen, method and preparation for every test that measures Growth Hormone. Select up to five tests to compare them side by side.
Labcorp 3 tests
Single-analyte tests
Growth Hormone 004275
Serum · Fasting not stated · Turnaround 4 days
Labcorp catalog pageMethod and collection
- Method
- Immunochemiluminometric assay (ICMA)
- Preparation
- Random growth hormone sampling should be performed on fasting patients who have rested for at least 30 minutes prior to collection. Growth hormone stimulation and suppression protocols are described in the online Endocrine Appendices: Growth Hormone Stimulation and Growth Hormone Suppression.
- Collection
- If a red-top tube is used, transfer separated serum to a plastic transport tube. Label tube with time of collection and patient's name.
- Reference notes
- 0.0−10.0 ng/mL
Growth Hormone Antibodies (Endocrine Sciences) 500144
Serum · Fasting not stated · Turnaround 5 - 10 days
Labcorp catalog pageMethod and collection
- Method
- Radioimmunoassy immunoprecipitation
- Collection
- Separate serum from cells within one hour of collection. Transfer specimen to a plastic transport tube before freezing. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested .
Growth Hormone, RIA (Endocrine Sciences) 500632
Serum · Fasting not stated · Turnaround 5 - 10 days
Labcorp catalog pageMethod and collection
- Method
- Double antibody radioimmunoassay (RIA)
- Collection
- Serum must be separated from cells within 45 minutes of venipuncture. Send serum in a plastic transport tube. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested .

Quest Diagnostics catalog pageMethod and collection
- Method
- Immunoassay (IA)
- Preparation
- Random growth hormone collection should be performed on fasting patients who have rested for at least 30 minutes prior to collection
- Collection
- Administration of STRENSIQ may interfere in certain assays and may falsely elevate values. For patients receiving STRENSIQ, consideration should be given to using alternate methods.

Verify these ranges and sources
We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
