Pre-analytical Variables (Spill the blood: Is it physiology or pathology?)
Learning Objective: At the end of this module, you will be able to describe the effects of pre-analytical variables on blood specimens.
Summary
Preanalytical is the phase between when the test is ordered and when the test begins.
- Preanalytical variables are divided into two which are controllable variables and uncontrollable variables.
Remember, the examples mentioned in this RLO are only a few of them and there are actually a lot more pre-analytical variables out there.
Pre-analytical variables are important in diagnostic analysis to get the correct result on the patients and protect them from any wrong result.
