What does a HemoCue test for?
HemoCue point-of-care systems are available to test blood glucose, HbA1c, urine albumin, Hb and white blood cells with five part differential counts. The systems give immediate results with laboratory accuracy.
What is the measuring range for the HemoCue HB 201 system?
0 – 256 g/L
The instrument has a measuring range of 0 – 256 g/L. Results above 256 g/L are displayed as ‘HHH’.
How does a HemoCue work?
The HemoCue system utilizes the principle of oxidation of haemoglobin to hemiglobin by sodium nitrite and the subsequent conversion of hemiglobin to hemiglobinazide by sodium azide. The reagents for these reactions are contained within a small disposable microcuvette of approximately 10 microliters in volume.
How should the HemoCue HB 201 Microcuvettes be stored?
Storage and handling of the HemoCue Hb 201 Microcuvettes The microcuvettes are to be stored at a temperature of 15–30 °C (59–86 °F) and in a dry place. Do not refrigerate. Use the microcuvettes prior to the expiration date that is printed on each package.
How accurate is HemoCue?
The HemoCue 201+ had a sensitivity (95% CI) of 99.1% (94.8–100.0) and a specificity (95% CI) of 71.0% (64.4–76.9).
What level of hemoglobin requires transfusion?
The American Society of Anesthesiologists uses hemoglobin levels of 6 g/dL as the trigger for required transfusion, although more recent data suggest decreased mortality with preanesthetic hemoglobin concentrations of greater than 8 g/dL, particularly in renal transplant patients.
What is Microcuvette used for?
The microcuvette is used for sampling the blood, as reaction vessel and as measuring cuvette.
Who owns HemoCue?
HemoCue Holding AB
HemoCue AB/Parent organizations
What does HHH mean on HemoCue?
3. If “HHH” is displayed, the result exceeds the measuring range of the HemoCue 201 plus. 4. If over range is displayed, the result exceeds the measuring range of the HemoCue 201 DM. 5.
What is hemoglobin count?
The hemoglobin count is an indirect measurement of the number of red blood cells in your body. When the hemoglobin count is higher than normal, it may be a sign of a health problem. Normal hemoglobin counts are 14 to 17 gm/dL (grams per deciliter) for men and 12 to 15 gm/dL for women.
