- Phonology: The study of the way sounds function within a particular language or languages. While phonetics concerns the physical production, acoustic transmission and perception of the sounds of speech, phonology describes the way sounds function within a particular language or languages.

polski), also known as the Mantoux test or PPD test, is a diagnostic tool used to detect an immune response to Mycobacterium tuberculosis, the bacterium that causes tuberculosis (TB).
Etymology
The term "tuberculin" derives from the word "tuberculosis" and the suffix "-in", indicating a substance. The "skin test" part of the name refers to the method of administration. The test is named after Charles Mantoux, a French physician who developed the test in 1907.
Procedure
The test involves injecting a small amount of tuberculin purified protein derivative (PPD) into the skin of the forearm. The injection site is then observed 48 to 72 hours later. If a hard, raised red bump has formed, the test may be positive, indicating TB infection.
Interpretation
The interpretation of the test depends on the person's risk factors for TB and the size of the reaction on the skin. A larger reaction (15 mm or more) is considered positive in people with no risk factors. Smaller reactions may be considered positive in people with certain risk factors, such as recent exposure to TB or a weakened immune system.
