Enrollment Process

Q: What are acceptable payment methods for my CTS subscription?
A: Payment may be made by VISA/MasterCard/AMEX or checks (in US dollars, drawn on a US bank). We do accept purchase orders; however, we invoice upon receipt of the purchase order, and our terms are Net Due as samples cannot be shipped until invoices are paid in full. International customers may opt to pay by wire transfer. Instructions are provided to customers who select that option.

We recommend that you read our Subscription Information and Policies before ordering.

Q: How will I know when my order is complete?
A: CTS confirms all subscriptions by e-mail. Please note this confirmation only indicates your order has been received. Your subscription is not complete until payment is made. If you pay by credit card or wire transfer you will receive a receipt via e-mail. You are also welcome to contact CTS to verify that we have received payment and that your order has been processed.

Test Data Submission

Q: Will CTS submit test results to accreditation bodies?
A: CTS submits test results to the following Accreditation Bodies (ABs):

American Society of Crime Laboratory Directors/Laboratory Accreditation Board (ASCLD/LAB)
ANSI-ASQ National Accreditation Board/ANAB (ANSI-ASQ NAB/ANAB)
National Voluntary Laboratory Accreditation Program (NVLAP)
State Agricultural Regulators

All forensic proficiency test data sheets include an accreditation agency release form. Completion of this form allows those laboratories accredited by ASCLD/LAB or ANSI-ASQ NAB/ANAB to authorize the release of their test results to the appropriate Proficiency Review Committee (PRC).

NVLAP informs CTS of its accredited labs and requests results.

ALP data is submitted by CTS to the various state agricultural regulators in accordance with the agencies' requirements.

CTS does not routinely submit results to other Accrediting Bodies; these ABs may have policies for self-submittal of results or review during assessment. Please contact your AB for further instructions.
