QA1 Haematology screening

This is a routine haematology/haemostasis screening package which offers Hb, RCC, MCV, WCC, platelets, reticuloctyes, PT, APTT and fibrinogen as the analytes. Surveys are issued every two weeks and there are 24 trials per year. Samples are dispatched on Tuesday to be tested by 11.00am on Wednesday of the following week.  For non UK participants, samples are dispatched 4 days earlier to allow more time for delivery.

Participants enter results online via the CQAS web site and, currently also fax or email them to the scheme which allows statistical analyses, production and posting of a report on the same day. Work is ongoing towards participants printing or downloading their reports from the web site in a pdf file.

Closing date and report issue – same day

Rolling twelve month cumulative performance graphs are issued every 6 trials for both blood count and routine coagulation.

Scheduled blood film analysis is provided on a quarterly basis. 

In addition, control calibration exercises for PT/APTT/Fibrinogen are dispatched intermittently at no extra cost.
