Serology unit of the FBI laboratory gathers and analyzes blood samples from a crime scene

Technicians working at the serology unit of the FBI (Federal Bureau of Investigation) laboratory. A technician collects blood sample from a shirt belonging to a suspect. The examiner drops benzidine reagent and dilute hydrogen peroxide into the blood sample in cotton swab. The blood sample turns blue. The examiner writes down notes and cuts a sample from the shirt for microchemical hemoglobin test. He places the sample on the microscope slide. The examiner applies a reagent on the sample in the microscope slide. The slide is warmed before being placed under a microscope. The examiner uses the microscope. Red crystals indicating the presence of hemoglobin found under a microscope. The examiner runs test for origin and blood group of the sample. The examiner also gathers samples from the unstained part of the cloth. The samples are placed on test tubes which are placed on a rack. The examiner marks the locations where the samples were taken in the clothing. The examiner writes notes on his worksheet. Blood serums are added to the samples. The rack containing samples are placed inside a refrigerator overnight. The examiner brings out a vial containing liquid blood sample from the same refrigerator. The liquid blood sample is centrifuged, and samples are gathered for a liquid blood grouping slide. Testing solutions are added to the samples. The slide is agitated to expedite the grouping reaction. The examiner reads the slide through a microscope. The examiner brings out vials of samples from blood-stained fabric gathered the day before. The test tubes are placed on the centrifuged machine. Blood samples on vials are placed in small rack. The examiner determines blood sample to be of human origin. Centrifuged grouping samples are placed in grouping slides to determine blood type. Examiner reads samples microscopically. A technician fills out a worksheet.
