Laboratory Turnaround Time Calculation
Calculate the average turnaround time (TAT) of the laboratory by dividing the total time by the number of tests.
Average Turnaround Time (TAT)
60,0dakika
It is the average time from request to result approval; a short TAT improves clinical decision speed and patient flow.

Scientific and theoretical basis
Laboratory turnaround time (Turnaround Time, TAT) is the average time from a test request to the approval of the result, and it is a key indicator of laboratory efficiency.
Formula and Logic
Average TAT = Total Turnaround Time / Number of Tests
TAT encompasses pre-analytical (sample collection, transport), analytical (device), and post-analytical (approval) phases.
How is it interpreted?
A short TAT improves the speed of clinical decision-making and patient flow; it is particularly critical for emergency and urgent tests. A long TAT may result from pre-analytical delays or device/labor force bottlenecks.
Considerations
Separate TAT should be monitored for emergency (STAT) and routine tests. LIS and device integration reduce post-analytical delays.

How is TAT (turnaround time) calculated?
The total turnaround time is divided by the number of tests to find the average TAT.
