Reliability, value, flexibility and frequency make our Forensic Biology and DNA proficiency tests the most popular in the industry. The Forensic Biology Series and the DNA Sample Specific Series are scheduled so that participants can choose tests from either series and remain in compliance with the FBI Quality Assurance Standards (QAS) test frequency requirements. Our schedule allows you to start at almost any time during the year. So if you have a new analyst to be tested, CTS has you covered. In addition, CTS recognizes that some examiners work in very specialized roles; the needs of those analysts are addressed in the Other Biology/DNA Tests category. Hundreds of laboratories participate, assuring test validity that just can't be found elsewhere. But you won't have to wade through hundreds of results; instead you receive a clear and concise report for each test, specific to your laboratory and sent only to you.
This series contains 6 individual tests; each test is issued once per year and allows nine weeks (from shipment to data due date) for examination. All sample sets will contain two known bloodstains and two suspected dried body fluid stains. Participants may report results for screening tests and STR/YSTR analyses for all tests; mtDNA testing is available on select test offerings. The known bloodstain samples are dried on either Whatman FTA Micro cards or cloth substrates. Finally, CTS structures its forensic biology offerings to assist laboratories in meeting the FBI Quality Assurance Standards (QAS) test frequency requirements. This series and the DNA Sample Specific series are scheduled so that participants can choose tests from either series and remain in compliance with those requirements.
This DNA testing series can be purchased any time during the year and is shipped once payment is received. Sample sets are customized per specifications chosen at the purchasing stage. Choose from a casework-like or reference-only test series. Known samples can be on FTA cards, cloth or swabs. Questioned samples can be on swabs or cloth. Pick whether the questioned samples have neat blood or mixtures. Participants may report results for STR and YSTR analyses. Return results on a flexible schedule and receive a report immediately upon submission.
This series contains 6 individual tests; each test is issued once per year and allows nine weeks (from shipment to data due date) for examination. All sample sets will contain two known bloodstains and two questioned stains that are pre-screened; thus, no screening data will be collected for this testing series. Participants may report results for STR and YSTR analyses. The known bloodstain samples are dried on either Whatman FTA Micro cards or cloth substrates. Finally, CTS structures its DNA sample specific offerings to assist laboratories in meeting the FBI Quality Assurance Standards (QAS) test frequency requirements. This series and the Forensic Biology series are scheduled so that participants can choose tests from either series and remain in compliance with those requirements.
The DNA Database Saliva test is offered twice a year and allows participants to choose from three different substrate options. All sample sets contain three saliva standards for testing, provided on the specified substrate. Tests that ship at the same time are not unique and will contain saliva standards from the same sources. The substrates available include GE Healthcare Whatman FTA Indicating Micro cards, Bode Buccal DNA Collectors and Puritan Cap-Shure Cotton Tip Swabs. Participants may report STR and/or YSTR analyses. CTS has structured the DNA Database Saliva test offerings to assist laboratories in meeting the FBI QAS semi-annual external proficiency testing frequency requirements.
The processing of forensic biology samples encompasses many different steps, each with the potential of being performed by different analysts in different locations within a laboratory system. CTS recognizes this and has developed tests to meet the needs of individual analysts in task specific roles.
