Hemolysis is conventionally defined as membrane disruption of red blood cells and other
blood cells that is accompanied by subsequent release of intracellular components into the …

Hemolysis represents an important source of error associated with the pre-analytical phase.
Improving the protocols for detection, measurement, management of the parameters affected …

We suggest here a pragmatic approach for managing results of clinical chemistry testing in
hemolyzed samples collected from adults/older children, attempting to balance the need to …

Two interferences recently brought to the forefront as patient safety issues include hemolysis
(hemoglobin) and biotin (vitamin B7). The International Federation for Clinical Chemistry …

Since the beginning of laboratory medicine, the main focus was to provide high quality
analytics. Over time the importance of the extra-analytical phases and their contribution to …

Potassium is one of the most requested laboratory tests. Its level is carefully monitored and
maintained in a narrow physiological range. Even slightly altered potassium values may …

Background Serum quality is an important factor in the pre-analytical phase of laboratory
analysis. Visual inspection of serum quality (including recognition of hemolysis, icterus, and …

Sample hemolysis is conventionally defined as the presence of a variable amount of cell-
free hemoglobin in serum or plasma. The reference (ie “normal”) concentration of free and …

Background Hemolysis is the most common type of preanalytical interference. Cut-offs
based on the hemolysis index level can be established using different approaches. The …

Background Although the effect of hemolysis has been extensively evaluated on clinical
biochemical tests, a practical guidance for laboratory staff to rapidly determine whether a …
