    Introduction

    ELISA (enzyme-linked immunosorbent assay) is a quick, easy and reliable test that can help to determine whether you have an infection or not. ELISA tests are available for many different types of infections and diseases, including HIV, lupus, Lyme disease and even allergies. The name comes from the fact that it uses antibodies linked to enzymes in order to detect molecules associated with certain infections or diseases. You can find out more about what kinds of ELISA tests exist below!

    Acute HIV Test.

    • Acute HIV Test: An ELISA test can help you determine if you're infected with HIV within a few weeks of exposure to the virus, before any symptoms appear.
    • Lyme Disease: A rapid test that detects antibodies against Borrelia burgdorferi (the bacterium that causes Lyme disease) may be used to diagnose infection in people who have been bitten by ticks carrying the pathogen and have symptoms such as fever, headache, fatigue, or joint pain within 30 days of exposure.3. Cystitis (bladder infection): The dipstick urine test is most commonly used as an initial screening method because it's relatively simple to perform and inexpensive—it can detect white blood cells in urine samples; however, false positives are possible so follow-up tests are often necessary for confirmation.
    • Hepatitis A: This antibody test looks for IgM antibodies specific to hepatitis A virus (HAV). HAV antibodies usually appear within two months after exposure but may take up to six months; therefore a negative result does not always mean that one hasn't had HAV recently.
    • Herpes Simplex Virus 1 & 2: These viruses produce similar symptoms including sores around the mouth or genitals (oral herpes), painful blisters on other areas of skin (genital herpes), itching around affected areas; fever; swollen lymph nodes in neck or groin area.

    HIV Western Blot Test.

    The HIV Western Blot Test is an immunological test used to detect antibodies to HIV in human blood. It is also used to confirm a diagnosis of AIDS in patients who have tested positive for antibodies to HIV by other means. This test can be used as part of the initial screening process for a number of diseases, including hepatitis and AIDS.

    The Western blot assay takes its name from its development at the University of California, Los Angeles (UCLA) by Drs. Zinder and Fisher in 1986/1987. The technique uses electrophoresis on gel medium that separates proteins based on their molecular weight, size, shape and charge characteristics; after migration through these media they are transferred onto nitrocellulose paper where they are detected with labeled monoclonal antibodies specific for antigens against various diseases such as syphilis or Zika virus infection etc..

    HIV Viral Load Test.

    • What is an HIV viral load test?

    The viral load test is used to measure the amount of HIV in your blood. This can be used to monitor treatment and help predict how well the treatment is working.

    The test uses a piece of equipment called an automated, enzyme-linked immunosorbent assay (ELISA) machine, which detects signs of the virus by measuring antibodies produced by your body's immune system against it.

    HIV-1 p24 Antigen Test.

    The HIV-1 p24 Antigen Test is a blood test that detects the presence of the HIV-1 protein, p24, in your blood. This antigen can be detected soon after infection with HIV or other strains of the virus.

    The p24 antigen test is not as accurate as viral load tests because it can take up to eight weeks before you may show positive results on this test. However, if you were infected with HIV recently then this could be a useful first step to confirm your status and then follow up with an accurate viral load test at a later date when more antibodies have developed in your system.

    The frequency of testing will depend on what stage you are at in terms of your disease progression – whether that be newly diagnosed or long term survivor (LTTS). As part of our routine monitoring program we recommend every six months for all patients who are still having sex with others outside their relationship and also every year for LTTSs who don’t have any other risk factors associated with transmission such as injecting drug use or sharing equipment etc

    Complement Fixation Test (CFT).

    A complement fixation test (CFT) is a type of ELISA that tests for the presence of antibodies to specific viruses. It is often used to diagnose viral infections such as Hepatitis B, Hepatitis C and HIV. Some physicians also use it to test for Lyme disease.

    Indirect Hemagglutination Assay (IHA).

    Indirect Hemagglutination Assay (IHA) is a test that looks for antibodies specific to the virus. This test is similar in nature to ELISA, with the exception that instead of using a solid-phase antibody, IHA uses red blood cells. In this test, red blood cells are mixed with the patient's blood sample and allowed to react with specific proteins from within that sample. If these proteins are present in your blood as a result of an infection or exposure (e.g., you have been infected by flu), your immune system will produce antibodies against them — and these can be detected via indirect hemagglutination assay.

    Fluorescent Antibody Virus Neutralization Test (FAVN).

    It is a rapid, highly sensitive and specific method for the detection of antibodies to HIV-1, HIV-2, or both. It can be used to test people who are at risk of contracting HIV to determine if they have been exposed or infected.

    Antibody titer is not affected by previous treatment with antiretroviral drugs; therefore, it can be used in patients who have been treated as well as those who have never received treatment before.

    Indirect Immunofluorescence Assay (IFA).

    An indirect immunofluorescence assay (IFA) is an ELISA test that uses fluorescent antibodies to detect specific antigens. This type of ELISA is commonly used to detect a variety of infections and diseases, including HIV, hepatitis B, hepatitis C and syphilis. It can also be used for testing for Lyme disease.

    Neonatal Screening Tests for Congenital Hypothyroidism.

    • Test name: Neonatal Screening Tests for Congenital Hypothyroidism
    • Test description: This screen checks the levels of TSH (thyroid-stimulating hormone), a hormone produced by the pituitary gland that stimulates production of thyroid hormones. The test is usually performed on newborns after birth and consists of taking a blood sample from a heel prick, which is then examined in a laboratory.
    • Normal results mean: If the TSH level is normal, it means there's no sign of hypothyroidism at this time but it may develop later on in life or not at all; if you're concerned about your baby's health you should consult your doctor about having him/her checked regularly for any symptoms related to this condition such as growth problems or delayed development.

    Immunoglobulin E (IgE) Allergy Testing.

    For allergy testing, the patient’s blood is collected and then exposed to a suspected allergen. If the allergen causes a reaction in the patient’s body (like an allergic reaction), then it will be detected by this test.

    The ELISA test is considered one of the most accurate ways to detect allergies because it can measure both IgE antibodies and IgG antibodies in your blood.

    Serologic Tests for Lyme Disease.

    Serologic tests for Lyme disease are used to measure the amount of antibodies against B. burgdorferi in your blood. ELISA is one type of serologic test that's commonly used, but there are many others.

    The advantage of ELISA over other types of tests is that it can detect low levels of antibodies that may not be detectable by other methods and at earlier times after infection than other tests. Another advantage is its accuracy: If your results come back positive, this means you probably have an active infection; if they're negative, then it's possible that you don't have Lyme disease at all (although this would usually require additional testing).

    ELISA tests are a great way to try to diagnose an infection early

    ELISA tests are a great way to try to diagnose an infection early. These tests are very accurate and can be used to test for many different types of infections. They are cheap, easy-to-use, and the first step in diagnosing an infection.

    Conclusion

    ELISA tests are a great way to try to diagnose an infection early. They require less time and money than other methods, and they can be used with many different types of infections. However, they do have some limitations that make them less useful in certain situations (such as when there are low levels of antibodies in the patient's blood).
