18/30 How to Set up a Medical Lab - Main Causes Of Hemolysis

Welcome to Needle.Tube, Your Personal Supply Assistant. Today, we'll briefly discuss: Main Causes Of Hemolysis.

Hemolysis during sample collection can significantly compromise the accuracy of lab results, making it crucial to understand its causes. One common cause is using a needle that is too small, which can shear red blood cells as they pass through, leading to hemolysis.

Excessive force during blood draw, such as pulling back too hard on the syringe plunger, can also rupture red blood cells. Improper mixing of the blood sample, particularly vigorous shaking, can cause cells to break apart and result in hemolysis.

Delayed processing or improper storage, such as leaving samples at room temperature for too long, can lead to cell breakdown. Using a tourniquet for too long before drawing blood can cause blood stasis, increasing the likelihood of hemolysis.

Collecting blood from a site where there is a hematoma can introduce hemolyzed blood into the sample. Understanding these causes and applying best practices in sample collection can minimize hemolysis, ensuring accurate and reliable test results.
