GEM® Premier 7000 with iQM3
Preanalytical errors can impact point-of-care testing. What might you be missing?
Hemolysis, the #1 source of preanalytical error1, while prevalent throughout the hospital, is often unrecognized. This can negatively impact potassium (K+) results and patient care.2 For the first time integrated on a blood gas system, the GEM Premier 7000 with iQM3 detects and flags hemolysis, in just 45 seconds.11
A breakthough in blood gas testing.

Hemolysis is the #1 source of preanalytical error¹
Preanalytical errors can affect the integrity of results in blood samples tested at the point of care (POC). Hemolysis accounts for up to 70% of all preanalytical errors and, while prevalent throughout the hospital, is often unrecognized. This can negatively impact potassium (K+) results and patient care.2
In vitro hemolysis can lead to:
- Inappropriate patient management3,6,7
- Decreased patient satisfaction6,8
- Inefficient staff/nursing time5,7,8
- Increased costs5,6,8
Hemolysis is prevalent throughout the hospital, and often unrecognized
Percentages indicate proportion of samples that are hemolyzed in each clinical setting

In a transformative step toward enhancing patient outcomes in acute care, GEM Premier 7000 with iQM3 provides lab-quality detection of hemolysis, in whole blood.
Informs and expedites critical decision-making3,6,12–16
Now with hemolysis detection, iQM3 ensures sample quality across the most common preanalytical errors (e.g., hemolysis, clots, bubbles). GEM Premier 7000 detects hemolysis in 45 seconds11 helping inform appropriate patient management decisions.
How is whole blood hemolysis detection possible?
GEM Premier 7000 with iQM3 utilizes patented technology for hemolysis detection. Based on a photometric measurement of whole blood, the hemolysis module includes:
