Full Name
Synonym: Mantoux-test
Therapeutic Action
Tuberculin purified protein derivative (Mantoux)
Biologic diagnostic agent
Indications
Skin test used as an aid in screening for infection by a tuberculous bacillus or as a pre or post-vaccination check for the BCG vaccine.
This test is used to diagnose tuberculosis infection :
- in children in countries with high-prevalence, particularly those in close contact with contagious cases, provided that a chest X-ray can be performed.
- in international staff who have already been tested, in order to detect a tuberculin conversion indicating a recent infection and to propose preventive treatment (after ruling out active tuberculosis).
Instructions for use
Multidose vial.
One dose (0.1 ml) is equivalent to 5 TU (Tuberculin Units) and contains 0.04 µg of tuberculin
Method of administration
Must be given by intradermal injection in the inner forearm.
Use a 1 ml graduated 1/100 syringe and a Luer needle 26G, brown, ID.
Evaluation of the reaction and interpretation
- The intradermal injection may cause an induration at the injection site, often accompanied by erythema. Only the induration is measured for test interpretation.
- The induration is measured transversely using a flexible ruler 48-72 hours post-injection by a trained healthcare professional.
- An induration of ≥ 5 mm is considered as a positive test result, which indicates infection with Mycobacterium tuberculosis. A phlyctenular reaction is considered highly positive.
- Induration and erythema typically will decrease after 4 days and disappear within 28 days.
- Results should be interpreted within the medical context, considering risk assessment and potentially complemented by radiography or other diagnostic evaluations.
Orders are always done in number of doses and not in number of vials!
Precautions for Use
Performing the test within 6 to 8 weeks of exposure to Mycobacterium tuberculosis may result in a false-negative result.
The test should not be used as a stand-alone tool for diagnosis of active tuberculosis disease. Risk assessment, radiography, and other diagnostic evaluations should also be considered for subjects suspected of having active tuberculosis.
