Article

Diagnostic performance of droplet digital PCR for KRAS mutation analysis in pancreatic cancer cytology specimens.

Research record from J Gastroenterol, 2026-05-23. PMID 42177316.

Glossary Term

Diagnostic Specificity

The probability that a test will produce a true negative result when used on non-effected subjects as compared to a reference or "gold standard". The specificity of a test can be determined by calculating: number of true negative results divided by the sum of true negative results plus number of false positive results.

DICER1 Gene

This gene is involved in the RNA interference pathway.

Glossary Term

Dideoxy Chain Termination DNA Sequencing

A DNA sequencing technique in which a mixture of deoxynucleosidetriphosphates (dNTPs) and chain-terminating dNTPs, which are radioactively or fluorescently labeled, are combined within the reaction mixture. Once the reaction is complete, the DNA strands are separated by size, and the labeled chain terminating dNTPs can be read in sequence by the investigator or by a machine.
