Can a bad blood draw affect results?

Phlebotomists can make any number of errors that compromise specimen integrity in ways that clinical laboratories cannot detect during the testing phase. And these “invisible” errors can cause false results. For example, faulty specimen collection techniques can bump up potassium readings by 1-2 mEq/L.

What are the sources of hemolysis during venipuncture?

Hemolysis resulting from phlebotomy may be caused by incorrect needle size, improper tube mixing, incorrect filling of tubes, excessive suction, prolonged tourniquet, and difficult collection.
