# Clinical Testing Guidance for Tuberculosis: Tuberculin Skin Test
## Key Points
- The tuberculin skin test (TBST) is a vital tool in diagnosing tuberculosis (TB).
- It involves injecting a protein derivative and reading the reaction after 48-72 hours.
- While effective, best legal steroids in medicine (somo.Global) it has limitations like false positives and requires trained personnel.
## Background
The TBST is commonly used to detect latent TB infections. It's based on a response to the Bacillus Calmette-Guérin (BCG) vaccine, indicating potential exposure to TB bacteria.
## About the TB Skin Test
The test involves injecting 0.1 mL of tuberculin antigen into the derma. After 48-72 hours, a healthcare provider reads the reaction for induration.
## Advantages and Disadvantages
### Advantages:
- Non-invasive.
- Cost-effective in many settings.
- Easy to administer once trained.
### Disadvantages:
- Pain at injection site.
- Potential false positives (due to other infections or BCG immunity).

## Boosted Reactions and keven da hulk steroids Two-Step Testing
Two-step testing involves a booster injection 2 weeks later if initial result is ≤5mm. This reduces false positives.
## Vaccinations
Live virus vaccines (like MMR) can affect TBST results, which of the following has been found to be a side effect of anabolic steroid use? necessitating consideration in test interpretation.
## Administering the TB Skin Test
Proper technique ensures correct placement and depth of injection to avoid errors.
## Interpreting Test Results
Classify reactions into positive or negative based on induration size: ≥5mm considered positive for latent TB.
## Classification of TB Skin Test Reactions
- Induration of 5+ mm: Positive.
- 10+ mm: Strongly positive, indicating active TB.
- 15+ mm: Indicates high exposure risk.
## Test Accuracy
False positives occur with other infections; false negatives may result from insufficient antigen exposure.
## What to Do with Test Results
Positive results require further investigation; negatives may need booster tests if exposure is suspected.
## Reminder
Proper follow-up and patient education are crucial after testing.
