According to this report the global latent TB market is expected to reach $1,684.86 million in 2027 from $1,131.82 million in 2019. The market is estimated to grow with a CAGR of 5.2% from 2020-2027. The growth of the market is attributed to the increasing prevalence of tuberculosis and government initiatives to promote tuberculosis detection. However, multi drug resistant tuberculosis (MDR-TB) is likely to hamper the growth of the market to a certain extent. Based on test, the latent TB detection market was segmented into tuberculin skin test (TST) and interferon gamma released assay (IGRA). In 2019, the tuberculin skin test (TST) segment accounted for the highest share in the market and is likely to retain its dominant share. The TST results are obtained in around 48-72 hours. Reading the presence or absence as well as the amount of in duration known as localized swelling does the reading of the test. Although TST is a basic test performed in high volumes, the inaccuracy in detection is likely to hamper the growth of the segment during the coming years. On the other hand, the interferon gamma released assay (IGRA) is expected to witness fastest growth in the market owing to the accuracy obtained through these tests.
