AFB/TB Susceptibility: Streptomycin (Rapid- MGIT)

AFB/TB Susceptibility: Streptomycin (Rapid- MGIT)

Streptomycin is an aminoglycoside antibiotic used in the treatment of Tuberculosis (TB), a severe infectious disease caused by Mycobacterium tuberculosis. This bacterium can develop resistance to streptomycin and other anti-TB drugs, leading to drug-resistant forms of TB. The AFB/TB Susceptibility: Streptomycin (Rapid- MGIT) test is a drug susceptibility test that determines the sensitivity or resistance of the TB bacteria to streptomycin.

The test employs the Mycobacteria Growth Indicator Tube (MGIT) method, a rapid, automated, non-radiometric detection system. It is used to detect the growth of mycobacteria in a liquid medium, providing rapid results to guide treatment decisions.

Frequently Asked Questions

This test is important to diagnose streptomycin-resistant TB, which is not responsive to treatment with streptomycin. Early detection of drug resistance is essential for effective disease management.

No, fasting is not required for this test.

Your doctor may recommend this test if you have been diagnosed with TB, and your condition is not improving despite treatment, or if you have been exposed to someone with drug-resistant TB.

This test measures the susceptibility of Mycobacterium tuberculosis to streptomycin. It helps in identifying whether the TB bacteria are resistant or sensitive to this drug.

The frequency of this test depends on the recommendations of your doctor, usually when drug-resistant TB is suspected.

A sensitive result indicates that the TB bacteria are likely to respond to treatment with streptomycin. A resistant result suggests that the bacteria are not likely to respond to this drug.

The main precaution is to provide an appropriate sample for the test. Follow the instructions provided by the healthcare facility or your doctor.

Factors that can affect the test results include improper collection of the sample, contamination of the sample, and technical issues with the testing process.

Modifiable factors include the method of sample collection and handling. Non-modifiable factors include the biological properties of the TB bacteria, such as natural genetic mutation leading to drug resistance.

If your test results indicate streptomycin resistance, you should consult a specialist in infectious diseases or a pulmonologist for further treatment.

No specific preparation is required. You should follow the instructions given by your healthcare professional for sample collection.

The test should be highly standardized, but slight differences may occur due to technical variances between labs.

The test itself poses no risk, but sample collection might cause minor discomfort.

Yes, you can eat and drink normally before the test.

Yes, streptomycin-resistant TB can be treated. However, it requires different combinations of anti-TB drugs and a longer duration of treatment.

This test plays a critical role in managing tuberculosis effectively, especially in areas where drug-resistant TB is prevalent. Identifying the resistance profile of the TB bacteria helps in customizing the treatment plan, thereby aiding in the patient's recovery and preventing the spread of drug-resistant TB. Prompt and accurate results from this test can significantly impact the treatment outcome and prognosis of the disease.
