Can you donate blood if you have taken growth hormone?
It depends on the type. Growth hormone made from human pituitary glands (used before 1985) means permanent deferral. Modern synthetic growth hormone does not by itself prevent donation.
Growth hormone (GH, somatropin) is prescribed for children with GH deficiency and for adults with certain pituitary conditions. For blood donation there are two very different cases.
Human derived GH (historic)
Before synthetic GH existed, it was extracted from the pituitary glands of cadavers. That product was linked to Creutzfeldt-Jakob disease, a fatal prion disease.
- If you ever received human derived growth hormone (generally before 1985), you are permanently deferred from donating
- The reason is the theoretical risk of prion transmission through blood
Synthetic recombinant GH (current)
The GH used today is made with recombinant DNA technology and does not carry that risk. It does not by itself prevent donation. What matters is the underlying condition:
- Isolated GH deficiency: generally compatible with donation
- Hypopituitarism with several hormone deficiencies: evaluated individually
- A pituitary tumor: may defer, depending on treatment
What to tell the screener
- That your GH is synthetic, not from human sources
- Why you take it
- The other medications you use
In short
Human derived GH means permanent deferral. Modern synthetic GH depends on your health. Always give the full treatment history.
