Tuberculin, also known as purified protein derivative, is a combination of proteins that are used in the diagnosis of tuberculosis.[1] This use is referred to as the tuberculin skin test and is recommended only for those at high risk.[2] Reliable administration of the skin test requires large amounts of training, supervision, and practice. Injection is done into the skin.[2] After 48 to 72 hours, if there is more than a five to ten millimeter area of swelling, the test is considered positive.[2]
Common side effects include redness, itchiness (pruritus), and pain at the site of injection.[1] Allergic reactions may occasionally occur.[1] The test may be falsely positive in those who have been previously vaccinated with BCG or have been infected by other types of mycobacteria.[2] The test may be falsely negative within ten weeks of infection, in those less than six months old, and in those who have been infected for many years.[2] Use is safe in pregnancy.[2]
Tuberculin was discovered in 1890 by Robert Koch.[3] Koch, best known for his work on the etiology (cause, origin) of tuberculosis (TB), laid down various rigorous guidelines that aided the establishment between a pathogen and the specific disease that followed that were later named Koch's postulates.[4] Although he initially believed it would cure tuberculosis, this was later disproved.[3] Tuberculin is made from an extract of Mycobacterium tuberculosis.[1]
It is on the World Health Organization's List of Essential Medicines.[5]
