Viral load results are reported as the number of HIV copies in one millimeter (mL) of blood. The lower the number, the less virus you have in your blood. Figures can range from several million copies to just 20 copies.

How do you read a viral load result?

Viral load test results are given in “copies per milliliter (ml)”. Each virus carries two copies of RNA. If 100,000 copies of HIV RNA are found, that means there are 50,000 virus particles (or virions).

How many copies to be undetectable?

The goal of HIV treatment is to reduce the viral load to an almost undetectable level. If your viral load is less than 40 to 75 “copies”—the number of HIV particles in a milliliter of blood—it will be considered “undetectable.”

What is a normal viral load?

Most doctors consider a viral load of 500 or fewer HIV RNA copies per mL to be low, while a viral load of 40,000 or more HIV RNA copies per mL is considered high.

When the viral load is high?

High viral load of SARS-CoV-2: increased transmission and frequency of symptoms. Patients with a high viral load of SARS-CoV-2 increase the risk of transmission from 12 to 24% and develop symptomatic disease more frequently.

What level is normal in CD4 and viral load?

Test results report CD4 counts in absolute numbers. There may be small variations between laboratories but the range of normal values ​​is between 500 to 1600 cells per cubic millimeter of blood (mm3). CD8 values ​​vary between 375 to 1,100 per mm3.

How to reduce viral load?

PEP (post-exposure prophylaxis) are medicines taken to prevent HIV infection after possible exposure (for example, if the condom breaks during sex and you don’t have an undetectable viral load). PEP must be started within 72 hours of possible exposure.

How long does it take to be undetectable?

“Undetectable” means that a test cannot detect the virus in the blood of a person living with HIV, even though extremely small amounts of HIV are still present. Someone who is undetectable for 6 continuous months or more, while on treatment, does not transmit the virus through sex.

When is a viral load undetectable?

A person’s viral load is considered “long-term undetectable” when it remains undetectable for a minimum of six months after first obtaining that viral test result.

How to know that I am undetectable?

In general, a viral load is considered undetectable when it is below 50 copies/mL; however, at present, the meaning of “undetectable” depends on the analysis method used in each hospital, and can be less than 20, 37 or 50 copies per milliliter.

What is it to be undetectable positive?

Having an undetectable viral load also helps prevent transmission of the virus to other people. For example, if your viral load is undetectable, you effectively have no risk of transmitting HIV to an HIV-negative partner through sex.

What does undetectable on a swab mean?

A negative result means no harmful bacteria or viruses were found in your sample. A positive result means that a specific type of harmful virus or bacteria was detected in your sample, pinpointing which specific type of infection you have.

What are normal CD4 and CD8 values?

A normal CD4/CD8 ratio is 2.0, with CD4 counts equal to or greater than 400/mm3 and CD8 counts between 200 and 800/mm3. If your ratio is greater than 2, it means your immune system is strong and you may not have HIV.

How much is normal for CD8?

CD8 cells are also part of the immune system and kill cancer cells and cells that are infected with a virus. Normal CD8 cell counts are between 150 and 1,000.

How many CD8 does a healthy person have?

CD8 cells, or suppressor cells, play a very important role in fighting infections such as HIV. Normally, a healthy person has between 150 and 1,000 CD8 cells per cubic millimeter of blood.

What does CD4 CD8 ratio mean?

The CD4/CD8 ratio is postulated as a potential marker of the immune status and the risk of complications.

What do you mean undetectable?

Undetectable is the same as non-transmissible, as long as adequate adherence to antiretroviral treatment is maintained, periodic viral load controls are carried out and the partner is stable.

What does detectable coronavirus mean?

Any suspected case of COVID-19 or asymptomatic person who presents a positive or detectable result by the following diagnostic techniques: Detection of SARS-CoV-2 through molecular biology tests by reverse transcriptase polymerase chain reaction (RT-PCR) .

What happens when a PCR is negative?

What does it mean that a PCR is negative? It means that, at the time the sample was taken, the test did not detect the virus in our body. And that can be so for two reasons, because you do not have the virus or because the viral load is so small that it is undetectable.

What if I am undetectable?

It means that the amount of virus in the blood is so low that the tests do not detect it. So if it’s Undetectable, it’s Untransmittable. It is important that you know that: If the treatment is suspended, this condition is annulled.

How long can you live with retrovirals?

Once a person is diagnosed with AIDS, they can have a very high viral load and transmit HIV to others very easily. Without treatment, people with AIDS usually survive about 3 years.

How long after having Covid does the PCR test negative?

A study advises repeating the PCR 4 weeks after symptoms appear. People who have had COVID-19 should have the PCR swab test again 4 or more weeks after symptoms first appear to minimize the risk of infection.

What does the PCR look at?

PCR, an acronym for ‘Polymerase Chain Reaction’, is a diagnostic test that makes it possible to detect a fragment of the genetic material of a pathogen.

When is the PCR negative?

Nasal or oropharyngeal PCR frequently becomes negative after the eighth day of symptoms,5 without being able to rule out with certainty that it could not have been negative days before.

When to swab for Covid?

When should a swab be performed to diagnose COVID-19? People who have SYMPTOMS compatible with COVID-19 (fever of 37.5°C or higher, cough, sore throat, shortness of breath, muscle pain, headache, diarrhea and/or vomiting, nasal congestion, sudden loss of taste) should be tested. or smell).
