Question

Dear Mr. Sowadsky, I realize that after a person donates blood, his/her donation is tested for HIV as well as other infectious diseases. Also, I have heard that blood donation centers alert people when their blood tests positive for HIV.

Answer

Hi. Thank you for your question. You are correct that if a person donates blood, and tests positive for one of the screening tests (including HIV), they will be notified by the blood bank that they have tested positive for one of the diseases that they are screened for.

When did blood donation testing start?

Blood donation screening for HIV-1, the causative agent of AIDS began with antibody testing in 1985. Many improvements in testing have occurred, including the detection of a second HIV agent (HIV-2 in 1992).

How long does it take for HBV to appear in blood?

Anti-HBc appears in the blood of individuals infected with HBV one to four weeks after the appearance of HBsAg, and at the onset of symptoms for those adults who develop symptoms (5% or less).

Where is babesia found?

Babesia is a red cell parasite endemic in the Northeastern and upper Midwestern regions of the US and responsible for the disease referred to as babesiosis. The parasite is naturally transmitted by the bite of an infected tick but may also be transmitted by blood transfusion.

What is the parasite that causes Chagas?

Trypanosoma cruzi (anti-T. cruzi) (2007) Chagas is a serious disease caused by the parasite Trypanosoma cruzi. The agent is endemic in Latin America, but approximately 20 reports of transmission by blood transfusion have been published worldwide.

When was the NAT test introduced?

A duplex nucleic acid test (NAT) was introduced for HIV-1/HCV RNA detection in 1999 and updated to include the detection of HBV DNA in 2009 (see above). Donors who test HCV-antibody reactive, but NAT nonreactive by routine testing are further tested individually for HCV RNA by NAT.

Can a virus cause a fever?

Infection may be asymptomatic or cause non-specific symptoms: fever, fatigue, headache, and muscle pain. In some cases, the disease can be severe, especially in those with a compromised immune system, hemoglobin-related diseases (such as sickle cell disease), and those lacking a spleen.

Why is blood donation screening important?

The purpose of blood-donation screening is to protect the blood supply. Consequently the sensitivity of the screening tests is set so that it will err on the side of protecting the blood supply. In other words, if the test picks up some false positives, no problem. The questionably positive blood can then be discarded.

What is NAT test?

In 2002 the FDA licensed the first NAT (nucleic acid test) for screening blood donors. NAT detects viral genes rather than anti-HIV antibodies or antigens (proteins from the virus). Viral gene detection allows for earlier detection, because the production of detectable antibodies, which is an immune response, requires time.

3.2.2: Precautions to reduce the transfusion transmission of prion-associated diseases

These include variant Creutzfeldt–Jakob disease (vCJD – caused by the same agent as bovine spongioform encephalopathy (BSE) in cattle – ‘mad cow disease’) and sporadic or inherited CJD. The following are permanently deferred from blood donation:

3.2.3: Blood groups and blood group antibodies

Every donation is tested to determine the ABO and RhD group of the red cells and the plasma is screened to detect the most common blood group antibodies that might cause problems in a recipient.

3.2.4: Molecular blood group testing

The genes for most human blood groups have now been identified. Currently only a limited number of patients undergo genotyping. These include recently transfused patients whose blood group is uncertain and fetuses that require typing to define the risk from maternal antibodies.

What does CBC mean in blood work?

Typical routine blood tests include the complete blood count (CBC) that measures your red and white blood cell numbers as well as hemoglobin and other numbers. Abnormal increases or decreases in these cell counts may indicate that you have an underlying medical condition that calls for further evaluation. But this is not a sensitive test ...

Can a blood test detect HIV?

Each test looks for a different thing. While there's no reason why the tests should n't include a specific test for HIV, this isn't necessarily routine practice.
