Hello,

First step may be,  You should confirm the identity of the sample ,  appropriateness of the sample and generate  the laboratory ID number for the sample. 

Agree with Daramesh

first is proper. sample identification,  then  reception chriteria as proper tube , proper anticiagulant , proper size of specimen

It depends...

I agree with Dr.

I agree with  Dr  Fatma  

You should clearly mention why you collect the samples, that means your research goal/objectives

It depends on what blood fraction you need i.e., serum, plasma, platelets, or WBCs.

Please, more details required!

Sample identification and identifying what tests are to be done with the samples comes first. That will determine how the sample will be handled, in terms of separation, storage and processing
