What is HIV and AIDS?
HIV stands for Human Immunodeficiency Virus. It is a virus that attacks the immune system, which is the body’s defense against infections and diseases.
If left untreated, HIV can lead to AIDS (Acquired Immunodeficiency Syndrome), which is a condition where the immune system is severely damaged, making the body vulnerable to infections and cancers.
HIV is transmitted through the exchange of certain body fluids, including blood, semen, vaginal fluids, and breast milk.
The most common modes of transmission are through unprotected sexual contact, sharing of needles or syringes, and from mother to child during pregnancy, childbirth, or breastfeeding.
There is currently no cure for HIV, but there are medications available that can help people living with HIV to live longer and healthier lives.
These medications are called antiretroviral therapy (ART) and work by suppressing the virus, reducing the amount of virus in the body, and preventing the progression of HIV to AIDS.
Public Health Context in Kenya
Kenya has made significant progress in the fight against HIV/AIDS in recent years. According to the National AIDS Control Council, the HIV prevalence rate in Kenya has declined from 6.9% in 2007 to 4.9% in 2017.
However, HIV remains a significant public health concern in the country, with an estimated 1.5 million people living with HIV as of 2020.
Kenya has adopted the UNAIDS 95-95-95 targets to end the HIV epidemic by 2030. This means that by 2025, 95% of people living with HIV should know their status, 95% of those who know their status should be on antiretroviral therapy (ART), and 95% of those on ART should have suppressed viral loads.
To achieve these targets, Kenya has implemented various strategies to increase HIV testing and treatment.
One of the strategies is the use of HIV self-testing kits, which were introduced in Kenya in 2017. HIV self-testing allows individuals to test themselves for HIV in the privacy of their homes.
This approach has been found to be effective in increasing HIV testing uptake, particularly among hard-to-reach populations such as men and young people.
Another strategy is the implementation of the “Test and Start” policy, which recommends that anyone who tests positive for HIV should start ART immediately, regardless of their CD4 count. This policy has been shown to improve health outcomes for people living with HIV and reduce the risk of HIV transmission.
Kenya has also implemented various initiatives to reduce HIV-related stigma and discrimination, which remain significant barriers to HIV testing and treatment. These initiatives include sensitization campaigns, training of healthcare workers, and the establishment of support groups for people living with HIV.
Types of HIV Tests
If you suspect that you may have contracted HIV, it is important to get tested as soon as possible. There are different types of HIV tests available in Kenya, and each has its own advantages and disadvantages. Here are the most common types of HIV tests:
Oral Test
The oral test, also known as the oral fluid test, is a type of HIV test that uses saliva to detect the presence of HIV antibodies. This test is performed by swabbing the inside of the mouth with a special device that looks like a toothbrush. After collecting the sample, it is sent to a laboratory for analysis.
The oral test is a convenient and non-invasive way to test for HIV. It does not require a blood sample, which can be uncomfortable for some people. Additionally, the oral test does not require any special preparation, such as fasting or avoiding certain medications.
However, it is important to note that the oral test may not be as accurate as other types of HIV tests. According to the National Syndemic Disease Control Council, the oral test has a sensitivity of 91.7% and a specificity of 99.9%.
This means that there is a small chance of a false negative result, especially if the test is taken during the window period when the body is still producing antibodies to the virus.
If you receive a positive result from an oral test, it is important to confirm the result with a follow-up test, such as a blood test. This will help to ensure that the diagnosis is accurate and that you receive appropriate treatment and support.
Overall, the oral test is a convenient and accessible way to test for HIV. However, it is important to understand its limitations and to confirm any positive results with a follow-up test.
Rapid Antibody Tests
If you need to get tested for HIV in Kenya, you have several options. One of the most common types of HIV tests is the rapid antibody test.
This test detects the presence of antibodies against HIV in your blood. If you have been infected with HIV, your immune system will produce these antibodies in response to the virus.
There are several different rapid antibody tests available in Kenya. Here are some of the most common ones:
Determine HIV-1/2
The Determine HIV-1/2 test is a rapid antibody test that can detect both HIV-1 and HIV-2 antibodies in your blood. This test is easy to use and provides results in just 15 minutes.
It requires a small blood sample, which is usually taken from a finger prick.
Uni-Gold Recombigen HIV-1/2
The Uni-Gold Recombigen HIV-1/2 test is another rapid antibody test that can detect both HIV-1 and HIV-2 antibodies in your blood. This test is also easy to use and provides results in just 10 minutes. It requires a small blood sample, which is usually taken from a finger prick.
SD Bioline HIV-1/2
The SD Bioline HIV-1/2 test is a rapid antibody test that can detect both HIV-1 and HIV-2 antibodies in your blood. This test is easy to use and provides results in just 15 minutes. It requires a small blood sample, which is usually taken from a finger prick.
While rapid antibody tests are convenient and provide quick results, they are not always accurate. False positives and false negatives can occur.
If you test positive for HIV on a rapid antibody test, you will need to confirm the result with a more accurate test, such as a Western blot or PCR test.
Laboratory Tests
In Kenya, there are several laboratory-based HIV tests available. These tests are highly accurate and can detect the presence of HIV in the blood. The laboratory tests include:
ELISA
ELISA (Enzyme-Linked Immunosorbent Assay) is the most commonly used HIV test. It detects the presence of antibodies produced by the body in response to HIV infection. ELISA is a highly sensitive test and can detect HIV infection within a few weeks of exposure.
However, it is not specific to HIV and can produce false-positive results due to cross-reactivity with other antibodies.
Western Blot
Western Blot is a confirmatory test that is used to confirm the results of the ELISA test. It detects the presence of specific HIV proteins in the blood.
Western Blot is highly specific to HIV and can confirm HIV infection with a high degree of accuracy. However, it is not as sensitive as the ELISA test and may produce false-negative results in the early stages of HIV infection.
Immunofluorescence Assay
Immunofluorescence Assay (IFA) is another confirmatory test that is used to confirm the results of the ELISA test. It detects the presence of HIV antibodies in the blood using fluorescent dyes.
IFA is highly specific to HIV and can confirm HIV infection with a high degree of accuracy. However, it is not as sensitive as the ELISA test and may produce false-negative results in the early stages of HIV infection.
Nucleic Acid Tests
Nucleic acid tests (NATs) are used to directly detect the genetic material of the HIV virus in a patient’s blood. These tests are highly sensitive and can detect the virus even in the early stages of infection.
NATs are typically used for confirmation of HIV diagnosis and for monitoring the effectiveness of antiretroviral therapy (ART).
Polymerase Chain Reaction
Polymerase Chain Reaction (PCR) is a type of NAT that amplifies the genetic material of the HIV virus in a patient’s blood. This test can detect the virus within days of infection and is considered the gold standard for HIV testing.
PCR is highly sensitive and can detect even small amounts of the virus in a patient’s blood. However, it is expensive and requires specialized laboratory equipment and trained personnel.
Viral Load Test
Viral load testing is a type of NAT that measures the amount of HIV virus in a patient’s blood. This test is used to monitor the effectiveness of ART and to detect treatment failure.
Viral load testing is highly sensitive and can detect even small amounts of the virus in a patient’s blood. It is recommended that patients on ART undergo viral load testing every six months to ensure that their treatment is effective.
In Kenya, NATs are typically performed in specialized laboratories and are not widely available in all healthcare facilities. However, the government of Kenya has made efforts to increase access to NATs in recent years.
The Tambua Mapema Plus (TMP) trial tested a combined HIV-1 nucleic acid testing, linkage, treatment, and partner notification intervention for adults aged 18-39 years with symptoms of acute HIV infection presenting to health facilities in coastal Kenya [1].

Point of Care Tests
Point of Care Tests (POCT) are rapid tests that detect the presence of antibodies against the HIV virus. These tests are the initial screening tests used to determine if a person has HIV.
POCTs are easy to use and provide quick results, which makes them ideal for use in remote areas where access to laboratory facilities is limited.
There are different types of POCTs available in Kenya, including the Determine HIV1/2 test and the OraQuick HIV test.
The Determine HIV1/2 test is a single-use rapid test that uses a small amount of blood from a finger prick to detect antibodies against HIV.
The OraQuick HIV test is a saliva-based rapid test that provides results in 20 minutes.
POCTs are highly accurate and have a sensitivity of over 99%. However, false positives and false negatives can occur, especially if the test is not used correctly or if the test is performed during the window period.
The window period is the time between infection with HIV and the development of detectable antibodies. During this period, a person may test negative for HIV even if they are infected.
POCTs are widely available in Kenya and are used in a variety of settings, including hospitals, clinics, and community-based organizations. The use of POCTs has increased access to HIV testing and has helped to reduce the stigma associated with HIV testing.
Self-Testing Kits
Self-testing kits are a relatively new addition to the HIV testing landscape in Kenya. They allow individuals to test themselves for HIV in the privacy of their own homes, without the need for a healthcare professional to administer the test.
As of 2017, the Kenyan government has made HIV self-test kits available through public and private health facilities and selected pharmacies for around US$8 each, a low price which was negotiated in a partnership between the government of Kenya and the private sector UNAIDS.
A study conducted in 2022 found that HIV self-testing is becoming increasingly popular in Kenya, with more and more people choosing to use self-test kits BMC Public Health.
The study also found that people who use self-test kits tend to be younger, more educated, and more likely to be male.
The vast majority of survey respondents view HIV self-testing as acceptable or would use HIV self-test kits, consistent with other literature from sub-Saharan Africa PMC.
The lack of difference by gender and by testing status suggests that self-testing could be an important tool in reaching those who have not yet been tested.
While self-testing kits can be a convenient and private way to test for HIV, they are not foolproof. There is a risk of false negatives, especially if the test is taken too soon after exposure to HIV.
It is recommended that individuals who test negative with a self-test kit should still seek confirmation from a healthcare professional.
Access and Availability of HIV Tests in Kenya
In Kenya, HIV testing is widely available and accessible. There are various types of HIV tests available, including rapid diagnostic tests (RDTs), enzyme-linked immunosorbent assays (ELISAs), and nucleic acid tests (NATs).
HIV testing is available in both public and private health facilities, including hospitals, clinics, and community-based organizations. The Ministry of Health has also implemented mobile testing services to reach remote and underserved populations.
The National AIDS and STI Control Programme (NASCOP) is responsible for coordinating and implementing HIV testing services in Kenya. NASCOP has developed national guidelines for HIV testing and counseling, which outline the different testing strategies and algorithms to be used in different settings.
HIV testing is provided free of charge in public health facilities, while private health facilities may charge a fee for testing services. The government has also partnered with various organizations to provide free HIV testing and counseling services in different parts of the country.
In addition to facility-based testing, HIV self-testing kits are also available in Kenya. These kits allow individuals to test themselves for HIV in the privacy of their homes. HIV self-testing kits are available for purchase in pharmacies and other retail outlets.
Final Thoughts
In conclusion, getting tested for HIV is an important step in taking control of your health. Knowing your HIV status can help you make informed decisions about your life and protect yourself and your partners.
Fortunately, there are several types of HIV tests available in Kenya that are accurate, convenient, and confidential.
The most common type of HIV test is the rapid antibody test, which can provide results in as little as 15 minutes. This test detects antibodies produced by your immune system in response to HIV infection.
However, it can take up to three months for your body to produce enough antibodies to be detected by this test, so it’s important to wait at least that long after a potential exposure before getting tested.
Another type of HIV test is the nucleic acid test (NAT), which detects the genetic material of the virus itself. This test can provide accurate results within a few days of infection, but it is more expensive and not as widely available as the rapid antibody test.
No matter which type of test you choose, it’s important to follow up with a healthcare provider for confirmatory testing and to discuss your results and any necessary next steps. Remember, HIV is a treatable condition, and early diagnosis and treatment can help you live a long and healthy life.
If you are living with HIV, it’s important to take your medication as directed and to practice safer sex to prevent transmitting the virus to others. There are also many resources available in Kenya to help you manage your HIV and live well, including support groups, counseling services, and treatment centers.
