AFB C/S (Wound Secretion for Mycobacterium Tuberculosis)

Specimen Required

WOUND SECRETION

Fasting Required

Purpose of the Test

The AFB C/S test on wound secretions is ordered when a person has a wound that does not heal or shows signs of infection, such as redness, swelling, and pus discharge. TB infection may cause skin and soft tissue infections, and the test helps in the diagnosis of TB infection in these cases.

When this test is required

The AFB C/S test on wound secretions is requested when a person is suspected of having TB infection in the skin or soft tissues. This may occur when a person has a persistent wound that does not heal or shows signs of infection, such as redness, swelling, and pus discharge. The test may also be ordered if a person has a positive TB skin test or TB blood test or if the TB infection is suspected to affect other parts of the body.

What the Test Detects

The AFB C/S (Acid-Fast Bacilli Culture and Sensitivity) test on wound secretions is used to detect the presence of Mycobacterium tuberculosis in a wound sample. This bacteria causes tuberculosis (TB), a contagious disease that primarily affects the lungs but can also affect other parts of the body, including the skin and soft tissues.

Preparation for the Test

There is no specific test preparation required for the AFB C/S test on wound secretions. However, your healthcare provider may ask you to stop taking certain medications that could interfere with the test results. It is essential to inform your healthcare provider about any medications you are taking, including over-the-counter drugs and herbal supplements, before the test. It is also important to collect the wound secretion sample properly to avoid contamination, and your healthcare provider will provide instructions on how to do this.

Sample Requirements

To perform the AFB C/S test on wound secretions, a sample of the pus or discharge from the wound is collected using a sterile swab or syringe. The sample is then sent to the laboratory for testing.

Additional Notes

It is important to note that the AFB C/S test on wound secretions is a complex and time-consuming test, and results may take several weeks to become available. Additionally, the test may have false-negative results, meaning that a person may have TB infection, but the test does not detect it. In some cases, repeat testing may be necessary to confirm the diagnosis. If you suspect that you have TB, you should seek medical attention immediately to get proper diagnosis and treatment.
