Please state the type of test material on the sample tube. Additional designation of the sample e.g. as EDTA plasma, citrat plasma would be helpful in this case for test classification. It is also necessary to state the time the sample was taken (for example before or after any stimulation).
The identity of the submitted sample must be unequivocal before it can be processed.
Please do a final check that all patient information like surname, first name, date of birth are stated on the sample tube and correspond to the information on the applicable requisition form laboratory, which is necessarily to fill out and to enclose.
