PT Datalink

PT Datalink is much more than on-line data entry. It includes simplified on-line data entry and modification screens. Drop-down screens for NELAC method and technology codes. Downloadable PT reports as pdf files. You can monitor, sort and review your PT results over time by methods and analytes in each FOT. We can electronically report results to accrediting authorities.

Have PT reports sent to as many accrediting authorities as you need without being “nickeled and dimed”. We do not charge for multiple reports. Make your PT planning easier by accessing preliminary results on-line within 24 hours of the study close. Rest assured your reports will be delivered to your accrediting authority securely and on time. We only use overnight express to provide PT results to your accrediting authority. This provides traceability and proof your reports were delivered on time!
