Hematological scan
A hematological scan was a type of medical scan.

While attempting to cure the Teplan blight, Julian Bashir ran a hematology scan on Epran. He noticed an unaccountable change in the viral base pair sequence. It was later discovered that the EM fields from his medical instruments were causing a mutation in the virus. ()

In 2374, The Doctor had Seven of Nine run a hematological scan on Neelix in order to regulate the dosage of nanoprobes for his next injection. While she performed the scan, he began to contemplate his own mortality, which agitated him to the point that she had to ask him to stop moving so she could complete the scan. ()
