TB Test Implementation and Benefits of Accreditation 4

Question 1

In an accredited TB testing program, what is the appropriate next step when a healthcare worker has a documented positive TST (≥10 mm) for the first time during annual surveillance?

Accepted Answer

Refer the worker for a medical evaluation, symptom assessment, and chest radiograph

Answer

A newly positive TST triggers a clinical follow-up evaluation including symptom review and chest X-ray to rule out active TB disease and determine whether preventive treatment for LTBI is indicated.

Question 2

Accreditation standards for TB testing programs typically require that PPD tuberculin be stored at which temperature range?

Accepted Answer

Refrigerated at 2°C to 8°C (35°F to 46°F)

Answer

PPD tuberculin must be stored between 2°C and 8°C and protected from light; improper storage can degrade the antigen and lead to false-negative results.

Question 3

Which documentation element is MOST critical in an accredited TB testing program to allow accurate longitudinal tracking of a healthcare worker's TB status?

Accepted Answer

Date of administration, lot number of PPD, site of injection, and exact mm of induration at reading

Answer

Complete records including administration date, PPD lot number, injection site, and precise induration measurement enable accurate future comparisons and TST conversion determinations.

Question 4

A facility's accreditation standards require that all staff involved in TB testing participate in annual competency reviews. Which scenario represents FULL compliance with this requirement?

Accepted Answer

Every staff member who administers or reads TSTs completes documented skills demonstration and written review annually

Answer

Full compliance requires both documented knowledge assessment and observed skills demonstration for every staff member performing TST-related tasks, renewed on the required cycle.

Question 5

Why do accreditation bodies specifically require facilities to use only FDA-approved tuberculin products for TST programs?

Accepted Answer

To ensure product safety, potency standardization, and reliable, reproducible test results

Answer

FDA approval ensures that tuberculin products meet standards for potency, purity, and stability, which are essential for accurate and reproducible TST results across different facilities.
