Definitive Test Results

When a specimen pool is tested multiple times for the same pathogen, our system automatically determines which result to use as the definitive (final) result.

Resolution Process

We use the following priority rules to select the definitive result:

1. Test Method Sensitivity (Highest Priority)

The result from the most sensitive testing method is considered definitive.

Example: If a pool was tested using both RT-PCR (high sensitivity) and RAMP (lower sensitivity), the RT-PCR result would be used.

2. Most Recent Test Date

If multiple tests used methods with equal sensitivity, the most recently performed test is considered definitive.

Example: If a pool was tested twice using RT-PCR—once in January and once in March—the March result would be used.

3. Most Recent System Entry

If tests were performed on the same date, the result that was most recently added to the system is considered definitive.

Example: If two RT-PCR tests were both performed on April 15th, but one was entered into the system on April 16th and another on April 20th, the April 20th entry would be used.

Important Notes

Result Types Considered

Under most circumstances, only definitive results are included in this resolution process:

  • Confirmed/Positive
  • Negative
  • Presumptive (in certain states)

The following result types are considered inconclusive and are not considered when determining the definitive result:

  • Inconclusive
  • Other
  • Pending

Why This Matters

This automated process ensures that:

  • You always see the most accurate and reliable test result
  • Results from more sensitive methods take precedence
  • The most up-to-date information is prioritized
  • Consistency is maintained across all test records
