Question

Which of the following methods are examples biotechnology used to assist blood analysis in medical forensics? Check all that apply.

the use of luminol to determine if blood was present

the use of blood typing to narrow down suspects

the use of DNA fingerprinting to see if a blood sample matches a specific person

the use of antibody testing to predict negative reactions to medications

Answer 1

Select:
- the use of blood typing to narrow down suspects — Yes. (Serological/biological methods used in forensic blood analysis.)
- the use of DNA fingerprinting to see if a blood sample matches a specific person — Yes. (Molecular biology/biotech methods central to forensic identification.)

Not selected:
- the use of luminol to determine if blood was present — No for “biotechnology” (luminol is a chemical reagent/chemical test used in forensics to reveal blood traces, but it’s not typically classed as biotechnology).
- the use of antibody testing to predict negative reactions to medications — No for forensic blood analysis (this is clinical/pharmacologic testing, not a routine forensic technique for analyzing blood at crime scenes).
