McCoy making out a lab report

McCoy working on the lab report

A lab report was the report of a laboratory analysis of a chemical substance.

In 2266, Doctor Leonard McCoy's lab report regarding the source of Kevin Riley's illness found a significant amount of tetra-lubisol. Spock concluded that someone had tried to poison Riley, rebuffing McCoy's suggestion that it was due to carelessness, given that Riley was one of the two last surviving witnesses (along with James T. Kirk) to the actions of Kodos the Executioner. He told McCoy that Kirk should see the report, and McCoy said the captain would when he had finished logging it. Spock insisted Kirk see it immediately.
