What is this test?
The catalogue labels this item as tuberculosis screening but does not specify a method, target, or specimen. It cannot safely be described as a skin, blood, molecular, or imaging test.
Why might it be ordered?
- When screening is required for a medical, occupational, or epidemiological reason.
- To proceed to a specifically confirmed method after discussion with a clinician or laboratory.
What sample is needed?
The catalogue does not describe the specimen or collection method clearly enough. Ask the laboratory which specimen is required for this exact test.
How should you prepare?
First confirm exactly which test is offered. Preparation, timing, and limitations differ between tuberculosis screening methods.
How should you understand the result?
The result cannot be explained without a stated method. Ask what the test measures and how reactivity is reported.
