In California, blood banks are required to test for HIV and notify donors of the results. Blood samples are drawn in separate tubes and tested for various infections, including HIV, hepatitis B, hepatitis C, and syphilis. The Central California Blood Center has implemented an FAQ page addressing concerns about blood donation, including HIV screening. Donors who report new or multiple sexual partners may be asked about anal sex within the last three months, resulting in a three-month deferral due to the increased risk of transfusion-transmitted HIV. Additionally, individuals who have taken antiretroviral therapy (ART) for HIV are permanently deferred from blood donation as ART does not eliminate the virus from the body. California law also mandates that blood banks display information about nearby sites offering free and anonymous HIV testing. These measures ensure the safety of donated blood and protect donors' health.

Blood banks must retest HIV-positive samples
In California, blood banks and plasma centres are required to retest HIV-positive samples for confirmation. This is outlined in the state's Health and Safety Code, which includes regulations to safeguard the consistency and accuracy of HIV test results. The code states that blood or blood components from donors initially found to have serologic evidence of HIV antibodies must be retested. Only if a subsequent test confirms the previous result can the donor be notified of a reactive outcome.
Retesting is essential to confirm the presence of HIV and reduce the risk of false positives. Blood banks employ various testing methods, such as Nucleic Acid Testing (NAT) and antibody screening, to detect HIV and other infectious diseases in donated blood. These tests are highly sensitive and specific, but retesting is sometimes necessary to ensure accuracy. For example, the Red Cross uses a duplex NAT for HIV/HCV RNA detection, and if a sample tests positive, it is retested individually to identify the specific virus.
In addition to retesting, blood banks also implement measures to prevent the transmission of HIV and other communicable diseases. Donors are required to complete health screening questionnaires to assess their risk of exposure to HIV or AIDS. Blood banks also provide voluntary means of self-deferral, such as forms specifying that the donation is for research or test purposes only. These measures help ensure that potentially infected blood is not used for transfusion.
The consequences of inaccurate HIV test results can be significant. In California, it is a felony offence to donate blood with knowledge of an HIV-positive status. Those convicted may face up to six years in prison. Additionally, the transmission of HIV or other infectious diseases can result in criminal charges if it is found that the infected individual acted with the specific intent to transmit the disease to another person. Therefore, retesting HIV-positive samples is a critical step to ensure the safety of the blood supply and protect both donors and recipients from potential harm.

Blood banks must notify donors of reactive results
Blood banks in California are required by law to notify donors if they are found to have reactive results for HIV. This is to ensure the safety of donated blood and to prevent the spread of the virus.
The California Health and Safety Code includes regulations for blood donation and the handling of infectious diseases, including HIV. According to the code, blood banks must retest any blood that initially shows serologic evidence of HIV antibodies to confirm the results. If the reactive result is confirmed, the blood bank is responsible for notifying the donor.
The code also states that blood banks should provide donors with information about sites where they can receive anonymous HIV testing. This allows donors to take proactive measures and access testing services if they are concerned about their HIV status.
Additionally, blood banks are required to implement voluntary means of self-deferral for donors. This includes providing forms or check-off boxes indicating that the blood is for research or testing purposes only and offering a telephone callback system for donors to inform the blood bank that their blood should not be used for transfusion.
To protect the privacy of donors, the code specifies that civil liability or criminal sanctions will not be imposed for disclosing test results to a local health officer if necessary to locate and notify a donor of a reactive result. This provision ensures that blood banks can make reasonable efforts to inform donors while maintaining confidentiality.

Donor screening includes a health questionnaire
In California, blood banks are required to test for HIV and other infections that could be transmitted through blood transfusion, such as syphilis, hepatitis B, and hepatitis C. This is done to ensure the safety of the blood supply and protect the health of recipients.
The health questionnaire is a self-administered form with check-off boxes, allowing donors to provide information about their medical history and any potential risk factors for HIV exposure. This confidential process ensures privacy and encourages honest disclosure. It is important to note that donors must answer these questions truthfully and to the best of their knowledge. Providing false or misleading information on the health questionnaire may have legal consequences and could pose a risk to the safety of the blood supply.
Individuals who report "yes" to certain questions on the health questionnaire may be deferred from donating blood for a specific period. For example, reporting multiple sexual partners in the past three months would result in a three-month deferral from the last occurrence due to the increased risk of transfusion-transmissible HIV. This deferral period is based on scientific evidence and ongoing work to address systemic barriers to donation while maintaining safety protocols.
The health questionnaire is just one part of the donor screening process, which also includes a brief medical screening and blood collection. The questionnaire helps identify potential risk factors for HIV or other infectious diseases, while the medical screening assesses an individual's current health status and suitability for blood donation. Together, these measures help ensure that donated blood is safe and does not pose a risk of transmitting infections or diseases to recipients.

Donor blood with HIV antibodies cannot be transfused
In California, blood banks test donor blood for various infections, including HIV, hepatitis B, hepatitis C, and syphilis. This is to ensure that the donated blood is safe for transfusion and does not pose any risk of transmitting infectious diseases to the recipient.
While blood donation is generally a voluntary and altruistic act, there may be rare instances where individuals knowingly donate blood with HIV antibodies. This could occur if a person is unaware of their HIV status due to a recent infection or a lack of testing. In such cases, they would not be criminally liable under California law, as they had no knowledge of their HIV status. However, if an individual is aware of their HIV-positive status and donates blood without disclosing their condition, they may face criminal charges and penalties, including up to six years in prison.
California has strict regulations in place to safeguard the safety of donated blood and protect recipients from the risk of HIV transmission. Blood banks are required to retest any donor blood that initially shows evidence of HIV antibodies to confirm the results. If the presence of HIV antibodies is confirmed, the donor is notified, and their blood cannot be used for transfusion. This is a critical step to prevent the spread of HIV through blood transfusions.
Additionally, blood banks in California must provide information about anonymous HIV testing and resources for prospective donors. This includes displaying notices at collection sites with details about nearby locations where free and confidential HIV testing is available. This measure encourages individuals to get tested and make informed decisions about their eligibility for blood donation.
It is important to note that individuals who have previously taken antiretroviral therapy (ART) for HIV treatment are permanently deferred from blood donation. This is because antiretroviral drugs do not completely eliminate the virus from the body, and there is still a potential risk of transmitting HIV through blood transfusion. By adhering to these guidelines, blood banks in California can maintain the safety and integrity of the blood supply, ensuring that donor blood with HIV antibodies cannot be transfused and protecting the health and well-being of transfusion recipients.

HIV-preventative medication research is ongoing
In California, blood banks are required to display notices at their collection sites providing information on nearby locations where anonymous HIV testing can be performed free of charge. Additionally, blood banks must retest any blood donations that initially show serologic evidence of HIV antibodies to confirm the results.
While HIV was once a fatal disease, it has now become a treatable and preventable chronic condition due to advancements in medical research. HIV-preventative medication research is ongoing, with the goal of developing new treatments that cater to the diverse needs of those affected by HIV.
For instance, Gilead, a leading innovator in HIV research, has developed Yeztugo Lenacapavir, the first and only FDA-approved HIV prevention medication that offers six months of protection. Lenacapavir is a twice-yearly injectable HIV-1 capsid inhibitor that disrupts the virus's capsid, preventing replication for about six months. This long-acting option is being evaluated in multiple ongoing and planned early and late-stage clinical studies, with the goal of offering both oral and injectable options with varying dosing frequencies.
The FDA's approval of Yeztugo Lenacapavir is supported by high efficacy and safety data from two clinical trials, PURPOSE 1 and PURPOSE 2. In these trials, Lenacapavir demonstrated superior prevention of HIV infections compared to daily oral Truvada, with an efficacy of 96% in the PURPOSE 2 trial. Lenacapavir addresses key barriers such as adherence and stigma associated with daily oral PrEP regimens, offering a powerful new tool in the mission to end the HIV epidemic.
While Lenacapavir has shown promising results, there are concerns about its affordability, with a list price of $28,000 per year. Gilead has stated that they are working on providing lower-cost alternatives, and researchers believe that the drug could be mass-produced for a much lower price.
