About this service

Tuberculosis (TB) film or AFB smear is a rapid and direct test for detecting acid-fast bacilli (AFB) in clinical samples such as sputum. It uses Ziehl-Neelsen staining or fluorochrome staining. These stains fluoresce the cell wall of mycobacteria (including Mycobacterium tuberculosis, the causative agent of tuberculosis) red, making them clearly visible under a light or fluorescent microscope. It is a rapid test but less sensitive than culture.

What is included?

✓Accurate analysis for diagnosing tuberculosis infection by microscopic examination of a sputum sample.
✓Consult a pulmonologist or infectious disease specialist to interpret the results.
✓Personal support services from Halak.

Conditions and notices

Fasting is not required
Sample type: 3 deep morning sputum samples (not saliva) collected on consecutive days in sterile containers.
The sample should be taken in the morning before consuming any food or drink, and the mouth should be rinsed thoroughly with water only before collecting the sample.
Samples should be brought to the laboratory as soon as possible after collection. If transport is delayed by more than an hour, they should be refrigerated (2-8°C).

Frequently Asked Questions

Short answers to the FAQs published with this service.

• What is a TB Smear (AFB Smear)?

It is a rapid microscopic test used to detect Acid-Fast Bacilli (AFB) in clinical samples like sputum as an initial step in diagnosing suspected active pulmonary tuberculosis.

• How does this test help determine infectiousness?

The test helps evaluate how infectious a patient is, as those with positive results—especially high positive results—are considered more likely to transmit the disease to others.

• Who should undergo a TB Smear test?

It is intended for individuals with a cough lasting over two weeks, contacts of confirmed active TB patients, and patients currently undergoing TB treatment for follow-up.

• Does a negative result rule out tuberculosis?

No, a negative result does not rule out TB infection, particularly if the bacterial count is low or the sample quality is poor.

• What symptoms suggest the need for this test?

Symptoms include a persistent cough for over two weeks (possibly bloody), fever, night sweats, unexplained weight loss, chest pain, or shortness of breath.

• Is fasting necessary before providing a sample for TB Smear?

No, fasting is not required for this microscopic examination.
