Explanation:

Analyze the question prompt

The question asks to select all options that represent types of tests used for determining tuberculosis (TB).

Evaluate the "PPD test" option

The PPD (Purified Protein Derivative) test is a standard skin test used to determine if a person has been infected with Mycobacterium tuberculosis. It involves injecting a small amount of PPD substance intradermally. Therefore, this option is correct.

Evaluate the "Scratch test" option

A scratch test (or skin prick test) is primarily used in allergy testing to identify hypersensitivity to specific environmental or food allergens. It is not used to diagnose tuberculosis. Therefore, this option is incorrect.

Evaluate the "Mantoux test" option

The Mantoux test is another name for the standard tuberculin skin test (TST) that utilizes Purified Protein Derivative (PPD). It is the primary skin screening method for tuberculosis. Therefore, this option is correct.

Evaluate the "Patch test" option

A patch test is a diagnostic method used to identify substances that cause allergic contact dermatitis. It is not used to determine tuberculosis infection. Therefore, this option is incorrect.

Answer:

• PPD test (Correct answer)
• Scratch test
• Mantoux test (Correct answer)
• Patch test
