ELISA: While ELISA (Enzyme-Linked Immunosorbent Assay) can be used to detect antibodies to the tuberculosis bacterium, it is not a direct method for diagnosing active TB infection. Direct methods include smear examination, culture, and nucleic acid technology, which detect the actual presence of the bacteria in the patient sample.

The reaction tested by adding concentrated sulfuric acid to a 24-hour peptone water culture is Cholera red reaction, This reaction tests for the presence of cholera vibrios, which produce hydrogen sulfide gas when their culture is acidified with sulfuric acid. The gas reacts with the ferric chloride present in the medium to produce a characteristic red color.

Suture materials are classified as either resorbable (absorbable) or non-resorbable (non-absorbable).

Non-resorbable sutures are made of materials that are not broken down by the body's tissues and remain in place until manually removed or permanently integrated.

Polypropylene is a synthetic, monofilament, non-resorbable material known for its low tissue reactivity and strength.

Resorbable sutures are designed to be absorbed by the body over time.

Polyglactin 910 (Vicryl) is a synthetic, braided, resorbable suture.

Catgut is a natural, resorbable suture derived from purified collagen.

Polyglycolic acid (Dexon) is also a synthetic, resorbable suture.
