Performance audits
Audit PAPP-A performance
- The measured PAPP-A is influenced by machine used to make the measurement, gestational age, maternal weight, height, racial origin, cigarette smoking, diabetes mellitus, method of conception, previous pregnancy with PE, gestational age at delivery and birth weight of the neonate in the previous pregnancy.
- However, the measurements also depend on the equipment and reagents used at a specific laboratory. You will therefore need to obtain the MoM values from your laboratory.
- To assess the quality of your measurements you need to upload an excel file providing data for each patient. For instructions on how the excel file should be formatted, please click here.
- The application will provide a distribution of MoM values that will be presented in two graphs. It will also assess the results and highlight whether your values are within or outside acceptable limits.
- If your results are outside acceptable limits, you will need to notify your laboratory to make the appropriate adjustments.
