Forensic Biology Tests

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 FTA Micro cards or cloth substrates. 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.

DNA On-Demand

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.

DNA - Sample Specific Tests

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 FTA Micro cards or cloth substrates. 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.

DNA Database - Saliva

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 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.

DNA - Advanced Technologies

The Probabilistic Genotyping test is offered twice a year and allows participants to choose from two different known sample substrate options. All sample sets will contain two known bloodstains and two questioned mixture stains. Participants may report results for screening tests, minimum number of contributors, STR/YSTR analyses using Probabilistic Genotyping software, and likelihood ratios. The known bloodstain samples are dried on either FTA Micro cards or cloth substrates. CTS has structured the Probabilistic Genotyping test offerings to assist laboratories in meeting the FBI QAS semi-annual external proficiency testing frequency requirements.

Other Biology/DNA Tests

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.
