Donating plasma can save lives and earn you a little money, but not everyone is eligible to donate. You can be disqualified for a range of reasons, from low iron levels and recent tattoos to certain medications and chronic health conditions. The rules exist to protect both your health and the safety of the plasma supply for patients who receive it.
What Disqualifies You From Donating Plasma?
The most common reasons for deferral fall into a few clear categories. These include current illness, low protein or hemoglobin levels, recent travel to certain countries, and specific medical diagnoses. Temporary disqualifications, like having a cold or getting a new piercing, usually clear up within days or weeks. Permanent disqualifications apply to conditions that always pose a risk, such as testing positive for HIV or hepatitis B or C.
Plasma centers follow federal regulations set by the Food and Drug Administration (FDA). They also follow additional standards from the industry. Every center uses the same core screening process, but some may have slightly stricter policies based on their own risk assessments.
Health Conditions That Prevent Plasma Donation
Certain chronic conditions will permanently disqualify you from donating plasma. These conditions either put you at risk during the donation process or raise concerns about the safety of your plasma.
Infectious diseases are the clearest permanent deferrals. If you have tested positive for HIV, hepatitis B, or hepatitis C, you cannot donate. The same applies to syphilis, though treatment may allow you to qualify later if testing confirms the infection is gone.
Heart and lung conditions are also disqualifying. Unstable angina, a recent heart attack, or uncontrolled high blood pressure can make the donation process dangerous. The physical stress of donating can strain your cardiovascular system. Some centers may allow donation if your blood pressure is well controlled with medication, but this varies by location.
Bleeding disorders like hemophilia disqualify you because the donation process involves needle insertion and the risk of prolonged bleeding. If you take blood thinners, you are also disqualified because these medications increase bleeding risk.
Autoimmune diseases such as lupus, rheumatoid arthritis, and multiple sclerosis are typically permanent disqualifiers. The concern is that antibodies in your plasma could potentially harm recipients, though research on this is limited. Many centers err on the side of caution and defer donors with these conditions.
Medications That Disqualify You From Donating Plasma
Many common medications do not disqualify you from donating plasma. But some do, either temporarily or permanently. The rules depend on how the drug works and whether it could harm a recipient.
Blood thinners like warfarin, apixaban, and rivaroxaban disqualify you while you take them. These drugs increase bleeding risk during and after the needle removal. You may be eligible a few days after your last dose, depending on the specific medication.
Insulin from animal sources disqualifies you, but human insulin does not. Most insulin used today is human insulin or analog, so this rarely applies anymore.
Isotretinoin (Accutane) disqualifies you for one month after your last dose. This acne medication can cause birth defects, and the concern is that it could appear in your plasma.
Finasteride and dutasteride, used for hair loss and enlarged prostate, also disqualify you. The deferral period lasts one month after the last dose for finasteride and six months for dutasteride.
Growth hormone from human sources is a permanent disqualifier due to the theoretical risk of prion diseases. Synthetic growth hormone may be allowed, but this depends on the center.
Some medications require a waiting period after your last dose. Others are permanent. The best approach is to list every medication you take during the screening interview and let the center determine your eligibility.
Recent Vaccinations, Tattoos, and Piercings
Getting a vaccine, tattoo, or piercing does not automatically disqualify you from donating plasma. The rules depend on what you received and when.
Most inactivated vaccines like the flu shot or COVID-19 vaccines do not require any waiting period. You can donate the same day if you feel well. Live vaccines like measles, mumps, rubella (MMR), chickenpox, and shingles require a waiting period, typically two to four weeks.
Tattoos and piercings require a waiting period only if done in a state that does not regulate tattoo facilities. In states with regulated tattoo shops, you may donate immediately if the facility uses single-use needles and sterile equipment. In unregulated states, the waiting period is typically three months. Piercings follow similar rules, and the piercing must be healed with no signs of infection.
The rules changed over the years as regulators gained more confidence in infection control practices at licensed facilities. Always ask your donation center about their specific policy.
Travel History and Deferral Periods
Travel to certain countries can disqualify you from donating plasma for a period of time. The concern is exposure to diseases that could be transmitted through plasma.
Travel to areas with malaria requires a deferral. The waiting period is typically three months if you visited a malaria-endemic area and you have not had malaria. If you had malaria, the deferral is three years after symptoms resolve. If you lived in a malaria-endemic country for an extended period, the deferral may be three years after leaving.
Travel to the United Kingdom, France, or Ireland for certain periods between 1980 and 1996 may disqualify you permanently. This relates to concerns about variant Creutzfeldt-Jakob disease (vCJD), commonly known as mad cow disease. The FDA has specific rules about cumulative time spent in these countries during those years.
These rules change as new disease outbreaks occur. For example, the Zika virus outbreak led to temporary travel deferrals in the past. Check with your donation center about current travel-related deferral policies.
Lifestyle Factors and Temporary Disqualifications
Several lifestyle factors can temporarily disqualify you from donating plasma. These are usually short-term deferrals that allow you to donate once the issue resolves.
Recent drug use disqualifies you. The rules vary by substance. Marijuana use is generally allowed in states where it is legal, though some centers still defer. Cocaine, methamphetamine, and other illegal drugs typically require a deferral period. Intravenous drug use carries a permanent disqualification because of the risk of blood-borne infections.
Alcohol consumption does not disqualify you by itself, but you cannot donate while intoxicated. Centers will defer you if you appear impaired.
Low iron or hemoglobin levels are a common reason for temporary deferral. Plasma centers check your hemoglobin before each donation. If your levels fall below the required threshold, typically 12.5 g/dL for women and 13.0 g/dL for men, you will be deferred. You can usually return once your levels recover.
Pregnancy disqualifies you during the pregnancy and for six weeks after delivery. The body needs time to recover blood volume and nutrient stores.
Recent surgery or hospitalization requires a waiting period. The length depends on the procedure and whether you received any blood products. Receiving a blood transfusion typically requires a one-year deferral.
Questions You Will Be Asked During Screening
Before every donation, you complete a health history questionnaire. The questions are detailed and personal. You must answer honestly because your plasma could affect someone else’s health.
You will be asked about recent illnesses, medications, hospitalizations, and travel. You will also be asked about sexual history, drug use, and any history of certain diseases. The questionnaire changes over time based on new scientific evidence and regulatory updates.
Your vital signs are checked before donation. Blood pressure, pulse, and temperature must fall within acceptable ranges. Your protein levels are also tested periodically because low protein can occur with frequent donations.
Being honest during screening is not optional. Giving false information on the questionnaire can lead to permanent deferral if discovered. More importantly, it could harm a patient who receives your plasma.
Frequently Asked Questions
Can I donate plasma if I have high blood pressure?
Yes, if your blood pressure is controlled and within acceptable ranges on the day of donation. Uncontrolled high blood pressure disqualifies you because of the physical stress of the donation process.
How long after getting a tattoo can I donate plasma?
It depends on whether your state regulates tattoo facilities. In regulated states with sterile equipment standards, you can donate immediately. In unregulated states, the waiting period is typically three months.
Can I donate plasma if I take antidepressants?
Most antidepressants do not disqualify you from donating plasma. You should list all medications during screening, and the center will determine your eligibility based on the specific drug.
Does getting a piercing disqualify me from donating plasma?
Not permanently. You must wait until the piercing is fully healed with no signs of infection. In regulated states, you may donate immediately after the piercing is done, but the site must be healed before donation.
