New for 2023 Distributions
Based on customer feedback, we will be making some changes to the following test designs:
Fingerprint Identification Test Design We will be reducing the number of known contributors from five (5) knowns to four (4) knowns and the the latent prints provided will be developed with a variety of processing techniques which may include powder, ninhydrin, and cyanoacrylate fuming with dye stain.
Probabilistic Genotyping Software Test Design The PGS test will no longer be purchased in conjunction with a Forensic Biology or the Forensic DNA test. The new Forensic Biology with PGS test and the Forensic DNA with PGS test will contain multiple known contributor samples, multiple samples of unknown stains and a complex mixture sample. Participants will be requested to utilize Probabilistic Genotyping Software to determine if any of the known contributors are present in the complex mixture.
Forensic Biology and Forensic DNA Test Designs The knowns for the Forensic Biology and Forensic DNA proficiency tests will be provided on untreated bloodstain cards. FTA treated bloodstain cards or swabs can be provided upon request at time of purchasing.
Tool Marks Identification Test Design The Tool Marks Identification test will be provided once per year during our Spring distribution (May).
Declared Double Blind and Static Proficiency Test Designs Forensic Assurance provides both Declared Double Blind and Static (Standard) proficiency test designs. Our Static proficiency test design allows for a more economical option while maintaining the quality that has been demonstrated with our Declared Double Blind tests.
Declared Double Blind Test Design: Each forensic practitioner will receive a test composed of randomly selected unknown and/or known proficiency testing items, with the correct answers being specific to each test. Participants will be unable to gain information regarding the answers to their test through discussions with others participating in the same testing cycle, or with those administering the test. These blind elements are incorporated into the design of our tests to reduce the effects of bias on testing results. Forensic Assurance proficiency tests are declared (the participant knows that they are taking a test).
Standard (Static) Proficiency Test Design: Each forensic practitioner will receive a test containing the same testing items/samples as others in their laboratory, with the correct answers being the same for all the tests. The test will be comprised of some of the same proficiency testing items used in the declared double blind test design and the samples used will be different for every testing cycle.
