Understanding turnaround time (TAT)
Turnaround time is influenced by specimen type, transport conditions, batching, and the complexity of the method used. If a test is urgent, confirm specimen requirements and cutoff times before collection to avoid delays.
Why specimen handling matters
Many “unexpected” results come from pre-analytical issues such as incorrect tubes, inadequate volume, delayed transport, or temperature exposure. Following the right collection and handling guide helps preserve analyte stability and improves accuracy.
How to choose the right test
Where multiple tests can answer a clinical question, selection should consider sensitivity/specificity, disease phase, and prior therapy. If you’re unsure, our team can advise on the most appropriate panel or confirmatory pathway.
