Viral Load Dashboard Indicator Guide
The table below summarises the metrics highlighted on the Viral Load home dashboard cards. Use it as a quick reference when interpreting the figures presented across laboratories and facilities.
| Indicator |
Definition |
| Samples Received |
Total number of Viral Load samples received in a particular PCR Lab including samples transferred to the same lab |
| Samples Rejected |
Total number of Viral Load samples rejected at point of receipt and at point of testing. |
| Samples Transferred |
Total number of samples that were transferred to another PCR Lab for testing |
| Total Tested |
Total number of Viral Load tests completed across PCR laboratories within the reporting window. |
| Unique Samples Tested |
Total number of Distinct samples that have been tested at least once during the reporting period excluding reruns. |
| Unique Patients Tested |
Total number of Distinct patients who had a viral load test during the selected timeframe. |
| Valid Result |
Total number of tests done that resulted in a valid outcome(This includes Target not detected, Target detected, and any valid result greater than 0 copies/ml). |
| <20 |
Total number of Viral Load samples with a result less than 20 copies/ml. |
| 20 - 199 |
Total number of Viral Load samples with a result between 20 and 199 copies/ml. |
| 200 - 999 |
Total number of Viral Load samples with a result between 200 and 999 copies/ml. |
| <1000 |
Total number of Viral Load samples with a result less than 1000 copies/ml. |
| Median TAT |
Median Turnaround Time (Median TAT) represents the middle value of all turnaround times recorded within a defined period in all PCR Labs. It measures the time interval between the start of a laboratory process (e.g., sample collection or receipt) and its completion (e.g., result verification or release). When all TAT values from all labs are arranged from shortest to longest, the median is the point at which half of the samples were completed faster and half took longer. |
| Results Approved
| Total number of valid results approved in the PCR Lab. |
| Results Accessed by EMR
| Total number of valid and approved results in a PCR lab accessed by EMR. |
| Lab Performance |
Composite performance score for PCR labs covering testing throughput, reporting timeliness, and other key KPIs. |
