Biospectral analysis
From Memory Alpha, the free Star Trek reference
A biospectral analysis is a medical scan to identify and verify organic and inorganic matter, including their bioelectric patterns.
In 2369 Data ran a biospectral analysis on the young quantum singularity lifeforms who were trapped in the engine core of a Romulan warbird. (TNG: "Timescape")
In 2370, Ensign Martinez was ordered by Doctor Crusher to contact Doctor Selar and tell her she should perform a biospectral analysis on the dead body of Ned Quint. (TNG: "Sub Rosa")
