What is a two step TB tuberculosis skin test and how is it documented?

Definition and Meaning of a Two-Step TB Skin Test

A two-step TB skin test, also known as a Tuberculin Skin Test (TST), is a method used to determine if an individual has been exposed to the bacteria that cause tuberculosis (TB). This test is particularly useful for individuals who may have been infected in the past but do not show symptoms currently. The two-step process involves administering two separate injections of tuberculin, a purified protein derivative, into the forearm, spaced one to three weeks apart. The first step establishes a baseline, while the second step serves as a booster to enhance detection of latent TB infection.

How to Use the Documentation of a Two-Step TB Tuberculosis Skin Test

Documentation for the two-step TB skin test is essential for medical records and employment requirements. It typically includes details such as the dates of the injections, the results of each test, and the clinician's signature. To effectively use this documentation:

• Record Dates: Ensure that the dates of both injections and readings are clearly noted.
• Measure Induration: Document the size of any induration in millimeters (mm), which indicates the test result.
• Clinician Signature: Include the signature of the healthcare provider who administered the test and interpreted the results.

How to Obtain the Documentation of a Two-Step TB Tuberculosis Skin Test

To obtain the documentation for a two-step TB skin test, individuals should follow these steps:

• Contact Healthcare Provider: Reach out to the healthcare provider or clinic where the test was administered.
• Request Medical Records: Formally request the medical records that include the TB test documentation.
• Check for Standard Forms: Some clinics may have standardized forms that include all necessary information for the two-step TB test.

Steps to Complete the Documentation of a Two-Step TB Tuberculosis Skin Test

Completing the documentation involves a systematic approach:

• Step One: Administer the first PPD injection and record the date.
• Step Two: Read the result of the first test within 48-72 hours, measuring the induration.
• Step Three: If the first test is negative, administer the second PPD injection 1-3 weeks later.
• Step Four: Read the result of the second test within 48-72 hours and document all findings.
