Does Csl Plasma Test For Herpes

There Are Two Common Blood Tests Used To Identify Herpes And They’re Often Misleading

Man with HIV donates plasma

“I had a patient once who underwent this test, which was positive, and was told she has herpes, which to her was devastating and life-altering,” Friedman says. “She burst into tears when I explained the significance or lack thereof with this test, which is very misleading.” There are two common blood tests used to identify herpes: IgG and IgM. The IgM test is still used by some doctors even though it has been denounced by the Centers for Disease Control and Prevention . According to the American Sexual Health Association , IgM tests can lead to deceptive results, as well as false assumptions about how and when a person acquired HSV.

And that’s not all: IgM tests fail to accurately distinguish between HSV-1 and HSV-2 antibodies, leading them to provide false-positive results for HSV-2. In other words, if you’ve been exposed to oral herpes , results of the IgM test could lead you to believe you’re positive for genital herpes, when in fact you simply have antibodies against HSV-1.

IgG tests, on the other hand, are more accurate, but aren’t without their own issues. For instance, ASHA says that while an IgG test can distinguish between HSV-1 and HSV-2, the problem is that the time it takes for IgG antibodies to reach a detectable level varies from person to person. This means that even with accurate results, someone could get a false-negative if they have the test administered too soon after contracting the virus .

Pregnancy Birth And Miscarriage

You cannot donate blood if you are pregnant. After giving birth, you must wait at least six months before donating blood.

Also, after a miscarriage, you must wait at least six months before donating blood.

An early miscarriage does not prevent blood donation.

Donating blood once in early pregnancy does not constitute a risk, and blood donation does not increase the risk of miscarriage. However, women attempting to become pregnant are advised to avoid blood donation, since those hoping to become pregnant should keep up a good haemoglobin level.

What Abnormal Results Mean

A positive test result may mean that you have syphilis. If the screening test is positive, the next step is to confirm the diagnosis with a more specific test for syphilis, such as FTA-ABS . The FTA-ABS test will help distinguish between syphilis and other infections or conditions.

How well the RPR test can detect syphilis depends on the stage of the infection. The test is most sensitive during the middle stages of syphilis. It is less sensitive during the earlier and later stages of the infection.

Some conditions may cause a false-positive test, including:

  • IV drug use
  • and some other autoimmune disorders
  • Tuberculosis

What You Should Know Before Donating Blood

Besides saving the lives of others, donating blood can be emotionally and physically beneficial. According to theMental Health Foundation, donating blood can:

  • Alleviate stress
  • Boost your emotional well-being
  • Prevent cardiovascular disease by reducing harmful iron deposits

Also, when you go to donate blood, you get a free health checkup. The checkup will identify whether you are healthy enough to give blood by checking your:

  • Pulse
  • Blood pressure
  • Hemoglobin levels

Failing the screening could mean that you have a health issue that you were unaware of, and you can seek help before it gets worse.

Donating blood is safe as long as you are a healthy adult. Since the medical personnel use sterile equipment for each donor, you dont have to worry about picking up diseases from other donors. However, depending on your physiology and other factors, you may briefly experience these side effects after giving blood:

  • Lightheadedness
  • Slight bruising, swelling, or bleeding where the needle entered your arm
  • Arm pain, numbness, or tingling

If you experience physical weakness after donating blood, it should pass after a while. You can speed up your recovery by resting with your feet up and drink lots of water, herbal tea, or broth.

If you drink or smoke, avoid doing either at least 12 hours before donating blood. Lastly, wear a sleeveless or short-sleeved shirt so that your blood-giving arm will be easily accessible.

Hypertension Or Low Blood Pressure

Hypertension and medication for it are not obstacles to blood donation if the blood pressure can be managed with the drug therapy. To ensure that the body has become used to the effects of the medication, drug therapy must have been started at least two weeks before donating blood.

Low blood pressure and dizziness

If you have low blood pressure, you may donate blood if you are asymptomatic without medication. If your low blood pressure causes symptoms of illness, you take a medicine that raises blood pressure, or if you have fainted because of your low blood pressure, we do not recommend that you donate blood.

Young people often have lower blood pressure, which, for most people, corrects itself with age.

Contraceptive Pills And Hormone Replacement Therapy For Menopausal Symptoms

Contraceptive pills, other contraceptives and hormone preparations used for menopausal symptoms are not an obstacle to blood donation.

The placing or removing of a contraceptive capsule under the skin results in one week deferral time only if stitches have been used in the procedure.

Wouldnt Testing Everyone Stop The Spread Of Genital Herpes

We dont know. There is no evidence that diagnosing genital herpes with a blood test in someone without symptoms would change their sexual behavior and stop the virus from spreading. In addition, without knowing the benefits of testing, the risk of shaming and stigmatizing people outweighs the potential benefits. For these reasons, testing everyone for herpes is not recommended at this time.

To donate plasma if you have herpes, the donor should meet all of the FDA eligibility requirements for donating plasma and be in good general health. The donation center may also require a negative response to a questionnaire about symptoms and behaviors related to blood-borne infections such as HIV/AIDS, hepatitis B, and hepatitis C.

Here are other eligibility requirements:

Why The Test Is Performed

The RPR test can be used to screen for syphilis. It is used to screen people who have symptoms of sexually transmitted infections and is routinely used to screen pregnant women for the disease.

The test is also used to see how treatment for syphilis is working. After treatment with antibiotics, the levels of syphilis antibodies should fall. These levels can be monitored with another RPR test. Unchanged or rising levels can mean a persistent infection.

The test is similar to the venereal disease research laboratory test.

Restrictions For Donating Blood If You Have An Std

There are varying timelines for when you can or cannot donate blood with STDs. When in doubt, reach out to your local blood bank and ask for their specific guidelines. You should not donate blood if you suspect you may have human immunodeficiency virus , acquired immunodeficiency syndrome , human T-lymphotropic virus , or hepatitis.

You can never donate blood if you:

  • Are HIV positive or receiving HIV treatment
  • Are HTLV positiveâ
  • Are a carrier of Hepatitis B or C

The American Red Cross says you should not donate if you have done any of the following in the past three months:

  • Were a sex worker
  • Are a man and had sex with another man
  • Had sexual contact with anyone who meets the above-listed criteria
  • Injected recreational drugs
  • Had a sex partner who is HIV or HTLV positive, a carrier of hepatitis B or C, or a partner who has injected drugs not prescribed by a doctorâ
  • Took Pre-Exposure Prophylaxis or Truvada for preventing HIV

If you contracted syphilis or gonorrhea, wait three months following completion of your treatment to donate blood. If you have chlamydia, HPV, or genital herpes, you can still donate blood if you meet the other eligibility requirements.

If You Have Genital Herpes Can You Donate Blood

Before discussing whether you can donate blood when you have herpes, we need to answer the question: Can herpes be transmitted through blood donation?

Previously, blood collection facilities allowed herpes carriers to donate blood as long as they did not have an active infection. Thats because many believed that herpes could spread only during intercourse or via direct skin-to-skin contact.

However,recent studies suggest that herpes may spread via blood transfusions, regardless of whether the infected has an active infection. Since there isnt enough evidence to support this theory, many facilities still accept blood from herpes carriers.

General And Local Anaesthesia

Depending on the scope of the procedure, type of surgery and your recovery speed, procedures performed under general anaesthesia or epidural anaesthesia prevent you from donating blood for one to six months.

Minor procedures performed under local anaesthesia prevent blood donation for one to four weeks.

Don’t Miss: Is It Hard To Date With Herpes

Doctors Don’t Advise Getting A Blood Test For Herpes Without Any Symptoms

Hilda Hutcherson, assistant professor of obstetrics and gynecology at Columbia University Medical Center in New York, is one of those doctors. “I usually dont do tests for herpes someone has a lesion or a sore, something I can see, I will do a swab and take it to a culture or check the DNA on the materials I removed,” she says. “If theres nothing there and I do a blood test and the blood test comes back positive, lets say its positive for type 1, what does that really mean? Most people are positive for type 1.” She adds that someone could be HSV-1-positive and either have or not have genital herpes. The result “doesnt mean much, and it makes people go crazy.”

Hutcherson’s motto is pretty simple: Why stress yourself over something if you haven’t seen anything especially when it’s something as common as herpes? “Let’s say they have a blood test come in positive but theyve never had a lesion. Now what? You may never get a lesion,” she says. It’s for this reason that she recommends people do not get tested for herpes unless they have a visible lesion that can be cultured and sent to a lab. Let’s say you get tested anyway and it comes back positive, despite the fact that you have no symptoms. What do you do?

Can You Donate Plasma If You Have Stds

Because plasma is part of your blood, the same rules apply if you have herpes, whether you have HSV-1 or HSV-2: Don’t donate plasma if any lesions or sores are actively infected. Wait until they’re dry and healed. Don’t donate until it’s been at least 48 hours since you’ve finished taking any antiviral treatment.Apr 21, 2020

Organ And/or Tissue Transplant

Recent organ or tissue transplants would disqualify you from being a donor. You have to wait for 3 months after the operation before become eligible.

In the case of dura mater or brain covering transplant, this results in permanent disqualification from being a blood or plasma donor. This is because of the possibility of CJD or other TSE transmission.

Reasons You Can Be Disqualified From Donating Plasma

The human blood is composed of different components: red blood cells, white blood cells, platelets, and plasma. Plasma is the liquid portion, which appears to be a light amber liquid when isolated. It makes up about 55% of your bodys total blood volume and contains around 92% water, 7% proteins, and 1% mineral salts, sugars, fats, hormones, and vitamins.

Plasma primarily serves as the vehicle for transporting nutrients , hormones,and water to the cells and organs throughout your body. Moreover, it transports metabolic wastes to the kidneys, liver, and lungs, wherein other processes happen for the safe excretion of wastes. Lastly, it also helps in the maintenance of blood pressure and pH of the body.

Syphilis Testing In Blood Donors: An Update


Syphilis, an ancient disease, is still a public health problem worldwide. The World Health Organization estimated that there are 12 million new cases of syphilis each year, with more than 90% occurring in developing nations. Moreover, in the past 30 years, through its association with an increased risk of human immunodeficiency virus infection, syphilis has acquired a new potential for morbidity and mortality.

The aim of this review is to update our understanding of various serological tests, their limitations and advantages in order to develop the skill of when and how to order them and interpret their results in an effective and significant manner.

  • Taken Pre-Exposure Prophylaxis or Truvada for preventing HIV
  • Had sex with someone who has HIV, HTLV, or Hepatitis B or C

Keeping Blood Transfusions Safe From Blood Parasite

This page was fact checked by our expert Medical Review Board for accuracy and objectivity. Read more about our editorial policy and review process.

In the U.S., blood donations are considered safe and contracting infections from blood transfusions is uncommon. Careful screening of potential donors through questionnaires and testing donated blood for various microbes protects the blood supply. A new report looked at the number of infections spread through blood transfusions and found that, although such infections are rare, the parasite Babesia is one of the most common causes of the infections that do occur.

According to the Centers for Disease Control and Prevention , Babesia infection, also called babesiosis, is most often spread by the bite of certain ticksthe same ticks that carry Lyme disease. The ticks are most common in the Northeast and Midwest U.S., and in the spring and summer. Less common ways to acquire babesiosis include transmission through a blood transfusion and from a mother to her baby during pregnancy and delivery.

Not everyone infected with the Babesia parasite develops symptoms, but some people can have non-specific, flu-like symptoms such as fever, chills, sweating, headache, body ache, loss of appetite, nausea and fatigue. The parasites infect red blood cells and can cause them to burst. In some people, this may lead to a serious condition called hemolytic anemia . Babesiosis can be life threatening, especially in people who:
