What happens when the crime laboratory gets it wrong? In this episode we discuss the issues with relying solely on laboratory accreditation to determine if a forensic science laboratory is doing the testing correctly, what happens when a lab fails as it did in Washington, D.C., and how other laboratories manage to recover and regain customer confidence. We explore how organizations like the Texas Forensic Science Commission work to ensure quality forensic science work by taking action and the better way for laboratories to respond and improve after a complaint.

Secrets From the Crime Lab - EP.1 How do you know the crime lab did it right?

Ensuring the validity of the crime laboratory’s test result is paramount. Ensuring that the lab is impartial, competent, and committed to confidentiality is an integral part of that assurance.
PLAN - DO - CHECK - ACT
Laboratory Accreditation demonstrates conformance with international standards, giving the customer of a crime laboratory confidence in the test results.

In this episode we explore the ISO/IEC standards specific to forensic testing and calibration laboratories. These standards apply to labs performing a wide-range of forensic tests: biology/DNA, bloodstain pattern analysis, drug chemistry/ controlled substances, toxicology, firearms, blood alcohol, friction ridge, fire debris and explosives, digital evidence, and many more.

This episode sets foundational knowledge for future episodes that will explore the issues, challenges, and scandals facing many laboratories and how having a robust quality assurance program is essential for driving improvements.

This week's discussion is all about consent and ethical use of genetic information, including DNA databases. I define and discuss what is meant by consent and informed consent and how it's related to the treatment of Henrietta Lacks and how her story triggered the development of ethical practices in medical science. What are the responsibilities of the forensic geneticist? The law enforcement investigator? What should you think about before volunteering a DNA sample...It's a big topic, and this is only the start if the discussion.

DNA as the "Biological Witness". Forensic DNA Phenotyping predicts the externally visible characteristics - i.e. what a person may look like - from their biological material. It has applications in criminal investigations when other leads have failed, missing persons identification, and anthropological research.
