What is Hemolysis?
What is a Hemolysis Test?
A hemolysis test assesses whether a material causes red blood cells to rupture when in contact with blood. The test simulates exposure by using anticoagulated whole blood and measuring hemoglobin release with a spectrophotometer. The results are categorized as:
- Non-hemolytic if the hemolysis index is <2%
- Slightly hemolytic at 2-5%
- Hemolytic at >5%
Both direct-contact and extract-based testing are performed to ensure the material’s safety under all relevant conditions.
ME-92 Hemolysis Study Summary
ME-92’s proprietary thin dense chrome coating, applied to 304 stainless steel, was tested by NAMSA, an accredited independent lab. The study included both direct-contact and extract testing using pooled rabbit blood.
- Direct Contact Hemolytic Index: 0.7%
- Extract Hemolytic Index: 0.0%
Results confirmed that ME-92 is non-hemolytic under both conditions, far below the 2% threshold required for medical-grade safety.
Why Hemolytic Activity Matters
For surgical tools, implants, and devices that interface with blood, biocompatibility isn’t optional—it’s essential. ME-92’s non-hemolytic performance demonstrates its reliability in safeguarding red blood cells and supporting patient health during invasive procedures.
