The TB skin test is commonly used among those who are infected with tuberculosis (TB). This test helps health care professionals identify persons who may have been exposed to infectious diseases through infectious means. The test can also be used by health care workers and family members who may have been exposed to an infected patient. The test is done by injecting a tiny amount of fluid into the upper layer of the skin, called the vermilion.
Diagnosing the TB skin test
A person who has been exposed to infected fluids through needle exchange or unguarded wounds is recommended to undergo one or more TB blood tests or a TB skin test. These tests help health care workers identify cases of infection that have not been diagnosed correctly. Health care workers who perform these tests should wear sterile gloves while collecting the fluid for testing. A positive test result indicates that someone in the household has been infected with TB. A negative test result indicates that the patient is healthy and shows no symptoms of infection.
Testing With Two Specific Tests
Most health care professionals use two specific tests to identify persons with potential exposures to infectious diseases: the TB DNA test and the TB surface antigen test (TRA). The first test, the TB DNA test, detects the genetic material from a small amount of infectious fluid. The sample is taken from bodily fluids such as blood, sputum, or vaginal secretions. When DNA is detected, a barcode pattern is generated that identifies the sample.
The TB surface antigen test (TTA)
The TB surface antigen test (TTA) is more sensitive and can identify if someone in the household has had exposure to TB. If symptoms are noted after exposure, a healthcare professional should consider tracing the disease through microscopic testing of possible soil or other infected areas.
Several TB Blood Tests
The symptoms experienced by children and others cannot always be accurately determined due to their youth. In cases of uncertainty, a healthcare professional can follow up on a TB symptom evaluation using one of the following recommended TB screening tests: The TB Blood Test, The TB spit test, or The TB Visual Examination. TB blood tests and TB spit tests are more accurate than sample preparation. There are several TB blood tests, including the IgM and IgG test, the TNMirus Assay, or the Myelogram.
Required Documentation for Diagnosis
To meet the healthcare professional’s needs for a complete, proper, and accurate tuberculosis disease diagnosis, they must have the required documentation. This documentation can be in the form of specific instructions or written orders from a physician or other healthcare professional regarding the recommended schedule of routine follow-up tests and treatments. Some TB medications are associated with certain risks or side effects. Before a person can be administered any of these medications. They must be evaluated for a TB infection by a healthcare professional.
TB Infection Requires Vaccination
As with all diseases, it is preventing TB infection requires vaccination. However, for those who already have a positive history of TB, vaccination may not prevent reinfection. That is why it is essential for those employed in high-risk occupations to be vaccinated against TB. Another effective way of prevention is the employment of personal protective equipment or PPE. A recommended safety practice for those in a high-risk profession is to wear an approved PPE while in a TB outbreak. As the material will prevent any contact with infectious material that could lead to infection.
Safety Measures For Health Care Workers
An example of this equipment is a unique healthcare worker gown with sleeves and a hat, gloves, and protective footwear. A cape or splint, used when patients with active TB symptoms are placed in a sitting position. Lastly, healthcare workers who have been in contact with patients who have already had a positive history of TB. They Need to undergo a strict TB skin test or other means of evaluating possible infection. While the results of these tests are not necessarily conclusive, they are still handy for researchers and clinicians.
