BACKGROUND Two commercial blood assays for the diagnosis of latent tuberculosis infection--T-SPOT.TB and QuantiFERON-TB Gold--have been separately compared with the tuberculin skin test. Our aim was to compare the efficacy of all three tests in the same population sample. METHODS We did a prospective study in 393 consecutively enrolled patients who were tested simultaneously with T-SPOT.TB an...
SETTING This study was conducted in a high tuberculosis (TB) burden area in Worcester, South Africa, with a notified all TB incidence rate of 1,400/100,000. MAIN OBJECTIVE To compare the predictive value of a baseline tuberculin skin test (TST) with that of the QuantiFERON TB Gold (In-tube) assay (QFT) for subsequent microbiologically confirmed TB disease among adolescents. METHODS Adolesce...

An easy-to-use tuberculosis skin test is developed with chitin microneedles that deliver purified protein derivative at the correct skin depth and result in a positive test in BCG-immunized guinea pigs.
Giant reactions to the tuberculin skin test are extremely rare and have been previously reported almost exclusively in patients with lepromatous leprosy. We herein report a giant tuberculin reaction associated with the homeopathic drug Tuberculinum in a patient with no evidence of active tuberculosis or leprosy.

BACKGROUND Screening and treatment of latent tuberculosis infection (LTBI) prior to anti-tumour necrosis factor alpha (anti-TNF-alpha) therapy has been shown to decrease the incidence of active tuberculosis (TB) by more than 80%, and is recommended by the British Thoracic Society. In the absence of a gold standard test for LTBI, conventional screening currently involves taking a clinical histor...
The avian phytohaemagglutinin skin test is being proved as an in vivo system for the evaluation an avian in vivo T cell mitogenicity. The test system was one week old Gallus domesticus broiler Chickens. Five replicates were done for each of the whole, 1:10 dilutions of each of 0.05 IU tuberculin, tetanus immunoglobulin and DPT vaccine as test materials. The evaluation parameters were the skin i...
