We revised performance thresholds to greater than or equal to 95.0% acceptable level and greater than or equal to 99.0% achievable level. FASP-S03a test: screen positive rate T21, T18, T13 screening and FASP-S03b test: detection rate T21, T18, T13 screening National performance of ST4a (see standard SCT-S05) in Q1 was 49.6%, higher than the previous quarter. The trend graph below shows England ST4a performance since the KPI was first published in Q1 2019 to 2020. Thresholds have not yet been set for this KPI. Due to COVID-19, during the Q1 (April to June 2020) time period newborn screening laboratories were instructed to relax blood spot acceptance criteria on samples that would normally have been rejected and to accept day 4 samples. Together these factors are likely to explain the reduced ‘avoidable repeat’ rate observed during Q1 2020 to 2021. Guidance is available on the FASP programme’s processes for ensuring seamless and safe screening across the whole pathway.

Eligible women is the total number of pregnant women booked for antenatal care during the reporting period, excluding women who: transfer in at before or at 23 weeks and 0 days who have a result from a screening test performed elsewhere in the NHS in this pregnancy Denominator: total number of T21, T18, T13 screening samples received in the screening laboratory in the reporting periodmake sure any ultrasound practitioner performing the NHS FASP screening or diagnostic ultrasound scans holds, as a minimum, the qualifications outlined in the FASP handbook make sure there is effective communication between maternity and ultrasound services, for example when interpreting services are needed Date standard updated: April 2022.

Sample did not arrive at the laboratory as specified in the specimen transport and storage section of the FASP laboratory handbook. T21, T18, T13 higher chance screening result is defined as a result from combined screening for T21 and or T18 and T13, or from quadruple testing for T21 using national cut off.Date standard updated: April 2022.
