TAT = Time from sample receipt to reporting of test results.
Formula:
TAT = (Date of Result Reporting - Date of Sample Receipt) × 24 hours
Steps:
1. Record date and time of sample receipt.
2. Record date and time of result reporting.
3. Calculate difference in hours.
Example:
Sample Receipt Date: 2023-02-15 10:00 AM
Result Reporting Date: 2023-02-20 02:00 PM
TAT = (2023-02-20 02:00 PM - 2023-02-15 10:00 AM) × 24 hours
TAT = 5 days × 24 hours
TAT = 120 hours
Types of TAT:
1. Analytical TAT: Time for analysis only.
2. Reporting TAT: Time from analysis completion to reporting.
3. Total TAT: Time from sample receipt to reporting.
Factors Affecting TAT:
1. Sample complexity
2. Test methodology
3. Instrumentation availability
4. Analyst workload
5. Quality control checks
Industry Standards:
1. USP: 3-5 working days for routine tests
2. FDA: 5-10 working days for batch release testing
3. EU GMP: 5-15 working days for batch release testing
Best Practices:
1. Streamline testing processes
2. Prioritize samples
3. Optimize resource allocation
4. Implement automation
5. Continuously monitor and improve TAT
