how old do you have to be to donate plasma

You usually need to be at least 18 years old to donate plasma at most standard plasma centers in the U.S., and also meet weight and health requirements.

Quick Scoop: Age Rules for Plasma Donation

• Most commercial plasma centers set the minimum age at 18.

• Many centers also have an upper age range , often around 64–74 years old , though this can vary by company and by country.

• Some blood and hospital-based programs allow 16–17-year-olds to donate with parental consent , but that is not universal and depends on local rules and the type of donation.

Typical U.S. plasma center requirements

Many large plasma companies list similar basic criteria:

• Age: 18 and older (some allow up to about 69–74 years).

• Weight: At least 110 lb (50 kg).

• Health: In generally good health and able to pass a medical screening.

Some places note that people over about 64–69 might be deferred more often or asked for extra medical clearance, since plasma production and overall health can change with age.

Why you see different answers online

If you browse forums, you’ll see people say “18 is the youngest, and the oldest depends on the center, usually 65–75.” That matches what many official sites say, but:

• A few programs that collect plasma for medical research (not typical commercial donation centers) explicitly mention 16–17 with parental consent or special review.

• Outside the U.S., age ranges can differ slightly; for example, some blood services list donation windows like 17–66 for plasma donation.

So the safest rule of thumb is:

For regular paid or commercial plasma donation centers:
You generally need to be 18 or older , weigh at least 110 lb, and pass health screening.

If you are under 18 and interested, or over your mid‑60s , the only reliable way to know is to:

1. Check the website of the specific plasma or blood center near you (they usually list age and consent rules).

2. Call and ask whether they accept donors your age and if parental consent or a doctor’s note is needed.
