• You can donate plasma with herpes as long as you have no active sores and have been off antivirals for at least 48 hours.
• Herpes is not a bloodborne infection and does not permanently disqualify you from donating.
• Be honest during screening, wait for outbreaks to fully heal, and check with your specific donation center for their guidelines.
Herpes simplex virus does not circulate through the bloodstream way HIV or hepatitis does. HSV lives in nerve cells and typically only reaches skin's surface during an outbreak. Research has shown that herpes DNA can appear in plasma during primary (first ever) infection, but it is not detectable in blood during recurrent outbreaks in otherwise healthy individuals.
Because of this, herpes is not considered a bloodborne infection in same category as HIV, hepatitis B, or hepatitis C. Those conditions permanently disqualify someone from donating. Herpes does not. It is treated as a temporary deferral, meaning you just need to wait until your outbreak has resolved before you can donate.
The NIH Blood Bank states directly that you cannot donate when herpes lesions are active, but you can donate once lesions are dry and nearly healed: NIH blood donation eligibility guidelines.
The specific requirements can vary slightly between donation centers, but general guidelines are consistent.
You must not have any active sores, blisters, or lesions at time of donation. This applies to both oral herpes (cold sores) and genital herpes. The sores need to be fully dried and in final stages of healing.
You should wait at least 48 hours after finishing a course of antiviral medication like valacyclovir (Valtrex) or acyclovir before donating. These medications are not harmful to a plasma recipient, but donation centers want to ensure your outbreak is genuinely resolved and not just being suppressed by drug.
You will go through a standard screening process that includes health questionnaire and a brief physical check. Be honest about your herpes status and any recent outbreaks. Everything you share with medical staff is confidential and is used solely to determine your eligibility.
If you are experiencing your very first herpes outbreak, most centers will ask you to wait longer before donating. A primary infection is more likely to produce detectable virus in blood compared to recurrent outbreaks. Waiting until initial infection fully resolves and your immune response stabilizes is safest approach.
Herpes is handled differently from several other sexually transmitted infections when it comes to plasma donation. Here is how other common STDs compare.
HIV, hepatitis B, and hepatitis C permanently disqualify you from donating plasma. These are bloodborne infections that pose a direct risk to recipients.
Syphilis and gonorrhea require a three-month waiting period after completing treatment. Once treatment is finished and you are symptom-free for three months, you can donate again.
Chlamydia and HPV generally do not disqualify you from donating, as long as you meet other standard eligibility criteria and feel well at time of donation.
If you are currently managing herpes and want to understand more about how infection presents and progresses, this article on herpes in different stages gives a clear visual guide. And if you are trying to tell whether a bump is herpes or something else entirely, this comparison on herpes vs pimple can help you figure it out before your appointment.
When you arrive, you will fill out a detailed health questionnaire that covers your medical history, recent illnesses, medications, and sexual health. A staff member will then do quick physical check that includes blood pressure, temperature, and hemoglobin test.
Plasma centers also test every donation for bloodborne pathogens including HIV, hepatitis B, and hepatitis C. Herpes is not part of standard plasma screening panel because it is not transmitted through transfusion under normal circumstances.
If you pass the screening, donation process itself takes about 60 to 90 minutes. Your blood is drawn, plasma is separated out, and your red blood cells are returned to you with saline solution. You can typically donate plasma twice within a seven day period, with at least one day between sessions.
Herpes does not prevent you from donating plasma. You just need to wait until any active outbreak has fully healed and you have been off antiviral medication for at least 48 hours. Be upfront with donation center staff about your medical history, and you will be guided through the process. Unlike HIV or hepatitis, herpes is not a bloodborne infection that permanently disqualifies you. Millions of people with HSV-1 and HSV-2 donate plasma safely every year.
