Introduction

Tuberculosis (TB) is an infectious disease primarily affecting the lungs, caused by the bacterium Mycobacterium tuberculosis. Rapid and accurate diagnosis is critical in managing TB, and test strips are one of the tools used for this purpose.

Purpose of Tuberculosis Test Strips

Tuberculosis test strips are designed to provide a quick and accurate method for detecting the presence of Mycobacterium tuberculosis. These strips are often used in settings where traditional laboratory facilities are unavailable or for initial screenings.

Mechanism of Tuberculosis Test Strips

The strips work on the principle of immunochromatography. They typically consist of a nitrocellulose membrane where specific antibodies are fixed. When a sample is applied to the strip, it migrates along the membrane, and if TB antigens are present, they bind to the antibodies, producing a visible line as an indicator.

Parameters and Numerical Analysis

• Sensitivity: Tuberculosis test strips have a sensitivity range of 70% to 90%, meaning they correctly identify TB-positive cases within this range.
• Specificity: Specificity is approximately 85% to 95%, indicating the rate at which TB-negative cases are correctly identified.
• Time to Result: Results are typically available within 15 to 30 minutes after application.
• Sample Requirement: Only a small sample (approximately 5 µL) of whole blood, serum, or sputum is needed.
