Pre-analytical Challenges Encountered with Capillary Blood Collection and Testing (Online CE Course)

(based on 792 customer ratings)

Alex Casapu, MBA, MLS(ASCP)CM
Reviewers: Kevin McNeil, MBA-HCA, MLS(ASCP)CM

It is very important that the healthcare providers collecting and testing capillary samples are properly trained and adhere to the policies and procedures in order to reduce errors and ensure quality results. Test results are only as good as the sample used for testing. This course is meant to help with such challenges and will point out where care needs to be taken at the different steps along the way in order to avoid pre-analytical errors.
