The above software version has an incorrectly defined calculation parameter in one of the proportion equations for ductus venosus pulsatility index (dvpi). dvpi was originally introduced in lifecycle version v4.0 rev2.The issue is caused by an unintended error in the normal likelihood crown – rump length (crl) independent proportion equation. the equation contains parameter crl instead of the correct parameter crl - 65. due to the issue, the obtained risk value is approximately four times higher than expected with mothers having high measured dvpi (dvpi = 1.5). risk calculation results are not affected when measured dvpi is lower than 1.5. the issue may increase the false positive rate of t13, t18 and t21 screening in case dvpi is applied in the risk calculation. in case the measured dvpi is greater than 1.5, a false high risk screening result is reported.

PerkinElmer is recommending that users immediately discontinue applying the DVPI in the routine screening program and review any high risk screening results in which the measured DVPI is = 1.5. These risk calculation results are not considered accurate and should be recalculated without applying the DVPI in risk calculation. A software update will be provided as a permanent correction.
