Appropriately Selected Nerve in Suspected Leprous Neuropathy Yields High Positive Results for DNA by Polymerase Chain Reaction Method.

Identification of DNA by polymerase chain reaction (PCR) is a reliable and an affordable method to confirm leprosy. DNA from 87 nerve samples (61 from paraffin blocks and 26 fresh samples) was extracted. DNA was amplified by PCR from 80/87 (92%) specimens.
