Anyone else having any false negatives with the urinary preg tests?
We are investigating a couple in our dept and apparently our gynae team are looking at it too after they have had some.
As part of our review we discoverd that the strips we use clearly say in the manufacturers leaflet that they must not be called a negative result before 5 minutes. There is a question mark that we may not have been doing this with every strip.
There are also quality control issues. Do any of you subject your strips to reference samples? ( again the manufacturers recommend that you do) and if so who does it?
Our Near Pt Testing bods are getting interested in external quality assessment schemes like NEQAS or WEQAS ( http://www.ukneqas.org.uk/ ). Anyone doing that?
Cheers
Peter
