FAQs for Chemistry and Toxicology

The chemistry department called and said a specimen was hemolyzed, and some tests may not be accurate. What is this and how can it be avoided?
Hemolysis is the destruction of red cells. It is generally caused by a traumatic or difficult venipuncture. It can also occur when blood is pulled through a syringe or IV site too quickly or with too much force.
