As a participant in our proficiency test program, you will receive control sera four times a year from your HUMANdistributor to determine the HumEQAS lab parameters. You then enter the resulting data online and can also access the test results directly through the web portal. Don’t have internet access? Not a problem: Your distributor will be glad to handle data entry for you. HUMAN evaluates the recorded results and issues a certificate confirming your successful participation. Your distributor will help with error analysis if there is any further need for improvement.
