Understanding the Aplisol Tuberculin Skin Test: A Step-by-Step Guide
The Aplisol Tuberculin Skin Test is a vital diagnostic tool used in the detection of tuberculosis (TB) infections. This simple, yet effective test has been a cornerstone in public health strategies to combat tuberculosis worldwide. In this comprehensive guide, we will delve into the nuances of administering the Aplisol Tuberculin Skin Test. This Step-by-Step Guide aims to provide detailed insights into the procedure, ensuring accuracy and reliability in results. For healthcare professionals and curious minds alike, understanding this method is crucial in the broader effort to control and prevent TB.
Aplisol Tuberculin Skin Test: The Basics
What is the Aplisol Tuberculin Skin Test?
The Aplisol Tuberculin Skin Test is used to determine whether a person has been exposed to Mycobacterium tuberculosis, the bacteria that causes tuberculosis. This test uses a purified protein derivative (PPD) to elicit a response from the immune system, revealing potential exposure.
How does it differ from Tubersol Skin Tests?
While both Aplisol and Tubersol are forms of purified protein derivatives used in skin testing for TB, they differ primarily in their formulation and production processes. These differences can marginally affect sensitivity and specificity in various populations.
Importance in Healthcare
Timely and accurate detection of tuberculosis is critical for both treatment and prevention. Implementing tuberculin skin tests like Aplisol or Tubersol is a widespread method in managing public health and ensuring effective control of infectious diseases.

Step-by-Step Guide: How to Administer the Aplisol Tuberculin Skin Test
Step 1: Preparation
Before administration, ensure you have all necessary supplies, including the Aplisol solution, a sterile syringe, and appropriate documentation materials. Verify the expiration date and storage conditions of the Aplisol vial to maintain its efficacy.
Refer to Step-by-Step Guide to Safe Aplisol Tuberculin Skin Test Administration for detailed preparation instructions.
Step 2: Patient Consultation
Inform the patient about the procedure, its purpose, and any potential reactions. Ensure that they have not received a TB vaccination or another PPD test recently, as these could affect results.
Step 3: Administration
- Select the Injection Site: Typically, the inner forearm is chosen. Ensure the area is clean and free of any scarring or irritation.
- Draw the Solution: Use a 1mL syringe fitted with a 27-gauge needle to draw 0.1 mL of Aplisol.
- Inject the Solution: Insert the needle intradermally at a 5 to 15-degree angle to ensure proper placement. A small, pale elevation of the skin (a wheal) should be visible immediately upon injection.

Step 4: Post-Administration Care
Instruct the patient to avoid scratching or applying pressure to the test site. Advise them to return for a reading within 48 to 72 hours to evaluate their skin’s reaction.
Step 5: Results Interpretation
- No Reaction: If the area shows no swelling or induration, it’s typically considered negative, although individual health status must be factored in.
- Positive Reaction: Swelling over a certain size (based on individual risk factors) might indicate TB exposure and should be followed by further investigation.
Comparing Aplisol with Tubersol Skin Tests
Though similar, Aplisol and Tubersol have unique attributes that may influence product selection:
- Aplisol: Known for consistent results across a wide demographic but may occasionally vary with epidemiological changes in TB prevalence.
- Tubersol: Preferred in certain regions due to its specific formulation stability.
Products like Tubersol Tuberculin Purified Protein Derivative (Mantoux) 5 mL (50 Tests) and Tubersol Tuberculin Purified Protein Derivative (Mantoux) 1 mL (10 Tests) Tween Stabilized Solution (Rx) Refrigerated Item are also available for varying test volumes and needs.
Conclusion
Understanding the Aplisol Tuberculin Skin Test is critical for healthcare professionals tasked with TB diagnosis and prevention. While it’s a straightforward procedure, precision in execution and interpretation is key to enhancing community health outcomes. Whether choosing Aplisol or Tubersol, ensure that the testing method aligns with your specific institutional protocols and patient needs. As TB remains a global health challenge, diligent testing is crucial in achieving broader eradication goals.
