Clinical Description
The Urinary LAM (Lipoarabinomannan) test is a diagnostic tool used primarily for detecting active tuberculosis (TB) by identifying the presence of LAM, a polysaccharide found in the cell wall of Mycobacterium tuberculosis.
This test is particularly valuable in cases where traditional sputum tests are ineffective, such as in pediatric patients or those unable to produce sputum.
Test Description
The Urinary LAM test involves the collection of urine samples to detect LAM antigens. This test can be performed using point-of-care (POC) devices, making it accessible and user-friendly. The assay is designed to provide rapid results, aiding in timely diagnosis and treatment decisions for TB.
Indications of the Urinary LAM Test
This test is indicated for:
- Patients suspected of having active TB, especially those with negative sputum smear results.
- Individuals with advanced HIV infection, where traditional diagnostic methods may fail.
- Pediatric patients who cannot produce sputum.
- Patients presenting with TB symptoms but showing no results from standard tests.
Patient Preparation/Instructions
- No special preparation is required from the patient prior to the test.
- Patients should provide a clean-catch urine sample to ensure accuracy.
- It is advisable to inform healthcare providers about any recent infections or illnesses.
Typical Reference Values
- A positive result indicates the presence of LAM and suggests active TB.
- Negative results do not rule out TB, especially in immunocompromised patients.
Turnaround Time
Results from the Urinary LAM test can typically be available within a few hours when conducted at a point-of-care facility. Laboratory-based tests may take longer depending on processing times.
