What does IGRA mean in UNCLASSIFIED
IGRA stands for Interferon Gamma Release Assays, representing a type of medical test used to diagnose various forms of tuberculosis (TB). The method was developed in the 1990s as an alternative to the traditional skin test. With IGRA, a small sample of blood is taken and analyzed in order to examine the patient’s immune response to infection with M. tuberculosis, which causes TB. If a sufficient interferon gamma release is detected in the sample, further diagnostic tests may be needed. IGRA can also help predict future progression of TB disease or recurrence after treatment.

Advantages
The main advantage of using IGRAs for diagnosing tuberculosis is its accuracy in comparison to other methods such as the tuberculin skin test or sputum culture analysis. Whereas these older methods have false positives rates ranging from 20-60%, IGRA results are more reliable when interpreted according to manufacturer guidelines; false positives are less common, making it easier for healthcare professionals to accurately identify TB infections and begin treatment sooner rather than later. Additionally, unlike the skin test that requires follow up visits due possible false negative results, IGRA results remain valid even when they initially come back negative – no additional tests or consultations required.
Essential Questions and Answers on Interferon Gamma Release Assays in "MISCELLANEOUS»UNFILED"
What is an Interferon Gamma Release Assay (IGRA)?
An Interferon Gamma Release Assay (IGRA) is a type of blood test used to measure the body’s immune response to certain bacteria and viruses. It works by measuring the amount of interferon gamma, a protein produced in response to infection, that is released into the bloodstream. IGRA tests are used to help diagnose conditions like tuberculosis, as well as detect latent infections that may not cause symptoms.
How does an IGRA test work?
An IGRA test works by measuring the amount of interferon gamma in the blood. During the test, blood samples are taken and placed in special containers with antigens specific to certain bacteria or viruses. These antigens trigger an immune response if they detect an active infection; this reaction leads to the release of interferon gamma. By measuring the levels of this protein, doctors can determine whether or not a person has been exposed to specific pathogens.
Who should get an IGRA test?
People who have been exposed to specific bacteria or viruses, such as those associated with tuberculosis, should get an IGRA test. Additionally, people who have had contact with someone known to carry these pathogens should also consider getting tested. People with weakened immune systems may be more likely to develop latent infections and therefore may benefit from having this test done periodically.
What is an abnormal result on an IGRA test?
An abnormal result on an IGRA test indicates that there may be active infection present and further testing is needed for confirmation and treatment options. An abnormal result does not necessarily mean that you have a disease; however, it does indicate that additional testing must be done in order determine if there is disease present and how best to treat it if it is found.
How quickly will I get my results after having an IGRA?
Most labs will provide results within 48 hours after taking your sample for testing; however this time frame can vary depending on the lab being used and any additional testing they may need to do before providing results. You should consult your doctor or lab about when you can expect your results so you can plan accordingly.
Can I do anything before taking my IGRA?
Before taking your IGRA you should discuss all relevant medical history with your doctor and inform them of any medications you are taking; both prescription and over-the-counter medications can interfere or influence your results so it’s important your doctor be aware of what substances are in your system prior to testing. Additionally, follow any fasting instructions provided by your doctor leading up to the test as eating before taking your sample could also alter the accuracy of results.
Is there any risk associated withhavinganIGRAtest?

Final Words:
Interferon Gamma Release Assays provide healthcare providers with an accurate and reliable method for determining if an individual has contracted tuberculosis. By helping diagnose cases sooner rather than later, IGRAs keep both patients and public health officials one step ahead in terms of preventing spread and controlling outbreaks of infectious diseases like TB. As we move forward towards more efficient means of diagnosis and evaluation of infection risk levels, IGRAs stand out as an important advancement for healthcare professionals world-wide.
