These figures are hence identical to those reported by Howanitz et al, (1) since a hemolysis
rate below 2.
The prevalence of a hemolysis
after PDA endocarditis is unknown.
index of 150 arbitrary units (AU), in one published study, was equivalent to a hemoglobin concentration of 19.
Since adopting the best practices in 2009, Sarasota Memorial has successfully maintained a hemolysis
rate of less than 1 percent overall across the health system - a rate well below the national average of 5-7 percent.
According to laboratory protocol, a hemolysis
level corresponding to an approximate hemoglobin concentration below 100 mg/dL is judged to be acceptable for testing.
The hemoglobin concentration was measured as a hemolysis
index (HI) (calibrated in milligrams per deciliter hemoglobin) on the Abbott c8000 analyzer.
QI have been trying to find a hemolysis
control for our COBAS INTEGRA and have been unsuccessful.
It is possible that an individual department may have a hemolysis
rate comparable to the ED rate; however, total specimen numbers for each department were not captured.
ATP concentration was plotted vs hemoglobin concentration to create a hemolysis
correction curve (Fig.
It is reasonable to expect a hemolysis
rate of less than 2%.
If the difference between potassium concentrations in samples with a hemolysis
index of 0 and those with a hemolysis
index of 1 through 10 was not significant, as assessed by using the above formula, then hemolysis was considered not to be clinically significant.
11877984) states that "there is no interference from hemolysis up to a hemolysis
index of 50 (approximate hemoglobin concentration: 50 mg/dL)".
