Growth Hormone, Seven Specimens
Use
The Growth Hormone, Seven Specimens test is primarily used for the assessment of growth hormone levels over time following treatment. This is particularly useful in the context of evaluating growth disorders and determining the effectiveness of growth-promoting drugs. The test requires multiple specimens collected at various time points which allows for the monitoring of hormone secretion patterns in response to specific stimuli. This information is critical in diagnosing conditions like growth hormone deficiency or growth disorders.
Special Instructions
This panel requires the collection of multiple tubes at different time points after administering a drug or treatment. Ensure coordination with the clinician before collecting specimens. Biotin supplementation can interfere with the test results; patients should discontinue it at least 72 hours before specimen collection.
Limitations
The test may show interference if the patient is on a high-dose biotin supplement, which should be discontinued 72 hours prior to specimen collection. The series of specimens should not be collected unless the patient receives the specified treatment (pill, shot, or glucola) after the initial sample draw. The specimens should not be collected without confirming the necessity and appropriateness of the series with the clinician.
