How Long Does It Take To Detect Hiv In Blood

How Long Does It Take To See The Signs Of Hiv

Real Question: How Long Does it Take to Test Positive for HIV?

The signs and symptoms of HIV may first appear within two to four weeks of infection. The stage in which the symptoms appear is called the stage of acute HIV infection. The symptoms appear due to the resistance or fight of the immune system against HIV. In the initial stage, the virus multiplies rapidly and spreads throughout the body. It targets and destroys the CD4 cells . As a result, the level of HIV in the blood and the chances of transmission at this stage are very high. It is crucial to recognize the early signs and seek medical help, since early diagnosis and treatment of HIV gets the best results.

Screening For Hiv In Pregnancy

If you’re pregnant, you’ll be offered a blood test to check if you have HIV as part of routine antenatal screening.

If untreated, HIV can be passed to your baby during pregnancy, birth or breastfeeding. Treatment in pregnancy greatly reduces the risk of passing HIV on to the baby.

What Happens When You Go For A Test

Normally, testing involves taking a small sample of blood from your finger or your arm, or an oral swab. This is where you rub the testing pen along your gums to collect cells from your mouth.

How long it takes for HIV test results to come back will depend on the type of test you are taking. If youre taking a rapid test, you will be given your results within 20 minutes. Other types of tests will be sent to a laboratory and it may take between a few days and a few weeks for you to receive a final result.

Tests these days are very reliable, but if your result comes back positive, you should have a second confirmatory test to double check your result. If this is also positive, you will get an HIV diagnosis, after which you can start treatment.

Remember, HIV treatment these days is very effective and people with HIV can live long and healthy lives just like anyone else.

Reducing The Risk Of Hiv Transmission

The most effective way to prevent HIV transmission during sex is to use a condom. Get a condom ready before any sexual contact occurs, since HIV can be transmitted through pre-ejaculate, vaginal fluid, and from the anus.

Lubricants can also help reduce the risk of HIV transmission by helping to prevent anal or vaginal tears. The right lubricants also help prevent condoms from breaking. Only water-based lubricants should be used with condoms, because oil-based lube can weaken latex and sometimes cause condoms to break.

The use of a dental dam, a small plastic or latex sheet that prevents direct contact between the mouth and the vagina or anus during oral sex, is also effective at reducing the risk of HIV transmission.

For people who may have a higher risk for contracting HIV, preventive medication is an option. Pre-exposure prophylaxis medication is a daily antiretroviral treatment.

Everyone at increased risk of HIV should begin a PrEP regimen, according to a recent recommendation from the US Preventive Services Task Force. This includes anyone who is sexually active with more than one partner, or is in an ongoing relationship with someone whose HIV status is either positive or unknown.

Although PrEP does provide a high level of protection against HIV, its still best to use condoms as well. PrEP provides no protection against STIs other than HIV.

What Is The Hiv Prognosis If Not Treated

If untreated, HIV infection will progress to AIDS and the mortality rate is 90 percent. Though it cannot be cured, with appropriate treatment and precautions, patients can live up to a normal life expectancy .

The cause of death in HIV is usually due to serious complications from unusual opportunistic infections because of a weakened immune system or side effects of antiviral therapy.

White Blood Cell Count

White blood cells are a subset of cells produced in bone marrow whose primary role is to fight infection. A white blood cell count is one of the panel of tests included in the CBC that measures not only the total number of leukocytes but also the different types of white blood cells in a blood sample, namely:

Within the context of HIV, an elevated WBC typically means that your body is fighting an infection. Other tests can then be performed to pinpoint the cause.

An elevation of certain white blood cells may indicate a specific type of infection or an allergic inflammatory response. For example, higher than normal eosinophils may suggest a parasitic infection like toxoplasmosis, while elevated basophils can develop in people with a hypersensitive drug reaction.

A decrease in white blood cells may be the result of HIV medications , a minor viral infection, or a major opportunistic infection like tuberculosis.

CD4 T-cell lymphocytes are a type of white blood cell that HIV preferentially targets and infects. For this reason, they serve as the primary marker of your immune status if you have HIV.

What Support Is Available

If you receive an HIV diagnosis, you can find help. Your healthcare provider can recommend support groups and counselors.

If someone tells you they are HIV-positive, they are telling you because they trust you. The time right after diagnosis can be very tough. You can support them in many ways:

  • Be a friend. While they may not be ready to talk about their diagnosis right away, show them you care by treating them as you did before.
  • Listen. Your friend may just need someone to listen to their concerns and fears. Be there for them.
  • Learn about the disease. The reference section of this article has additional information to learn about the condition.
  • Encourage them to seek treatment. Your friend may not realize they have options available. They do, and they can get treatment. Help them find it and stick to it.
  • Get help for yourself. While it will be a challenging time for your friend, you may need some support too. Talk to others a counselor, for example about any concerns or anxieties you may have.

How Long Does Seroconversion Take

The timeframe between when a person contracts HIV and when tests can detect the infection is known as the window period. Everyones immune system is different. This makes it difficult to predict how long this stage will last.

Scientists have developed sensitive blood tests since the early days of the HIV epidemic. Its now possible to detect HIV antibodies, as well as other components of HIV, earlier than ever before. According to the Johns Hopkins Bloomberg School of Public Health, most people test positive within a few weeks of contracting HIV. For others, it may take

During the window period, a person may develop symptoms similar to the flu or other common viruses that include:

  • swollen lymph nodes
  • rash
  • fever

Symptoms may last from a few days to a few weeks. And they may range from mild to severe. But its possible to pass through the early infection stage without experiencing any symptoms at all. During this time, a person may not even realize that theyve contracted HIV.

How Do You Get Hiv

How long can HIV go undetected with testing | HIV/AIDS

HIV infection can occur in the following ways:

  • Unprotected sexual intercourse, especially receptive anal intercourse
  • Multiple sexual partners
  • Sexually transmitted diseases: Chlamydia and gonorrhea infections increase the HIV transmission risk by three times syphilis raises the transmission risk by seven times and genital herpes raises the infection risk by 25 times during an outbreak
  • Sharing IV needles or injections
  • Receiving HIV infected blood products
  • Needle-stick injuries
  • Maternal HIV infection : The risk of transmission can be reduced at birth by practices like cesarean delivery and prenatal antiretroviral therapy in the mother, and antiretroviral therapy in the newborn immediately after birth

Can Hiv Be Transmitted During The Window Period

Its important to know that people can transmit HIV before seroconversion.

The time between exposure and the immune systems initial response is a period of acute HIV infection. Following the initial transmission, the amount of HIV in the body is extremely high. So is the risk of transmitting the virus. Thats because the body has yet to manufacture the antibodies needed to fight it, and its not yet receiving treatment.

During this stage, most people have no idea that theyve contracted HIV. Even if theyve been tested, they may have received a false negative result. This might lead to engaging in practices with known risk factors, such as sex without a condom, where a person could unknowingly spread the virus to other people.

Anyone who thinks theyve had a recent exposure should tell their healthcare provider. They may check the HIV viral load or prescribe preventive treatment for a month.

âThe important thing to remember is that the resolution of symptoms does not mean the infection is gone,â says Dennis Sifris, MD, an HIV specialist with the Lifesense Disease Management Group, located in South Africa. âHIV is not like hepatitis, which can spontaneously clear. HIV is forever and is better treated sooner rather than later.â

How Long Do I Need To Wait Before I Test

#TomorrowsDiscoveries: Detecting HIV prior to symptomsâDr. Gabe Kelen

Thereâs a window period between exposure to HIV and a positive test because it takes time for your body to either build a response to the infection or for the virus to replicate enough for a test to detect it. HIV window periods can vary.

For example, if you have unprotected sex on a Friday night, and get an HIV test Monday morning, the test wonât be able to detect HIV or an immune response to HIV yet. There hasnât been enough time for a positive result, even if the virus is in your body.

To get the earliest, most accurate result, first consider when you were exposed and whether youâre showing symptoms.

  • If you know exactly when you may have come into contact with the virus, take a test 3 months after that date. Tests 3 months after exposure should be 99% accurate.
  • If you are having symptoms of HIV, see your doctor right away. Your doctor may want to use a test that can look for the virus directly in your body.

If you believe someone has discriminated against you because of your HIV status, you may wish to consult legal counsel.

A note from Cleveland Clinic

Research has made significant progress in terms of what we know about HIV. But there is still more to learn. Until researchers find a vaccine, HIV will continue to infect people. If you or someone you love may be HIV positive, please seek help. Current treatments can help HIV-positive people live happy, productive lives.

What Is Acute Hiv Infection

How long does it take for a healthy person to show up HIV ...

There are three stages of HIV infection:

  • Stage 1:Acute HIVinfection
  • Stage 2:Chronic HIV infection
  • Stage 3:AIDS

Acute HIV infection is the first stage of the infection. Usually within two to four weeks of infection, two-thirds of those with HIV will experience flu-like symptoms. These symptoms may last for several days or even weeks. However, some people may experience no symptoms at all.

In this stage, there is a large amount of HIV in your blood, which is known as the viral load. Studies have noted incredibly high viral loads during the acute stage, meaning you are more contagious at this time.
