Plan your test

Sample
Pure growth of Mycobacterium tuberculosis complex on appropriate media in a sterile, screw-capped container, sealed in a plastic bag. Refrigerated transport is required. If a specimen has already been submitted for AFB culture or Mycobacteria identification, the pure growth isolated in the lab will be used for this test.
Results
Results are typically available within approximately 21 days. Confirm with the laboratory before booking.
Preparation
No special preparation is required for this test.
Test priceKSh 9,000

Payment: M-Pesa and card options can be confirmed during booking.

Start with fit

Is this the right test for you?

The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.

  • ✓Patients with suspected or confirmed tuberculosis.
  • ✓Individuals who have not responded to standard TB treatment.
  • ✓Patients with a history of exposure to drug-resistant TB.
  • ✓Monitoring treatment effectiveness in complex TB cases.
  • ✓Guiding selection of second-line TB drugs.

In plain language

What this test helps you understand

This test helps determine the susceptibility of Mycobacterium tuberculosis to Linezolid, an important antibiotic used in treating drug-resistant TB. It guides clinicians in selecting appropriate therapy for patients with suspected or confirmed drug-resistant TB, particularly those who have failed standard treatment regimens.
The Cultured AFB Antitubercular DST Linezolid Test is a diagnostic tool used to identify drug-resistant tuberculosis (TB). It is particularly useful for patients whose TB has not responded to standard treatments. This test helps healthcare providers understand if the specific strain of Mycobacterium tuberculosis causing the infection is sensitive or resistant to the antibiotic Linezolid. This information is crucial for selecting the most effective treatment plan and improving patient outcomes. The test measures the effectiveness of Linezolid against the bacteria. It is recommended for individuals with suspected or confirmed TB, especially those with a history of treatment failure or exposure to drug-resistant strains. Accurate identification of drug resistance allows for targeted therapy, reducing the risk of treatment failure and helping to monitor the effectiveness of ongoing treatment.

PreparationNo special preparation is required for this test.
SamplePure growth of Mycobacterium tuberculosis complex on appropriate media in a sterile, screw-capped container, sealed in a plastic bag. Refrigerated transport is required. If a specimen has already been submitted for AFB culture or Mycobacteria identification, the pure growth isolated in the lab will be used for this test.
MethodologyCulture-based drug susceptibility testing (DST) is performed to determine the minimum inhibitory concentration (MIC) of Linezolid against the cultured Mycobacterium tuberculosis strain.
PrivacyYour sample and report are handled confidentially. Ask the team how your information is stored and shared.
This test requires a cultured sample of Mycobacterium tuberculosis. Results depend on the quality of the culture and the specific strain tested. Confirm with the laboratory before booking.

Questions people ask

Frequently asked questions

Drug-resistant TB is tuberculosis caused by bacteria that are resistant to one or more of the standard antibiotics used to treat the disease.
This test helps identify if the TB bacteria are resistant to Linezolid, a key drug for treating drug-resistant TB. This information is vital for choosing the right treatment.
A sample of the cultured Mycobacterium tuberculosis bacteria is required. This is usually obtained from a previous TB culture test.
Results typically take about 21 days, but this can vary. Confirm with the laboratory before booking.
A positive result indicates that the TB bacteria are resistant to Linezolid, meaning this antibiotic may not be effective for treatment.
No special preparation, such as fasting, is required for this test.
