Specifications General The HemoCue Hb 201+ is a system used for the determination of the total amount of hemoglobin in whole blood. The system consists of a specially designed analyzer with specially designed microcuvettes containing dried reagents. The microcuvette serves as pipette, reaction vessel and as a measuring microcuvette. No dilution is required. The hemoglobin measurement takes place in the analyzer, which follows the progress of the reaction until the steady state has been reached. The system is factory calibrated against the hemoglobincyanide (HiCN) method, the international reference method for the determination of the hemoglobin concentration in blood, and needs no further calibration.
humidity. Use the HemoCue Hb 201 Microcuvettes prior to their expiration date. The expiry date is printed on each package. Storage of microcuvettes kept in a vial
The microcuvettes are to be stored at room temperature (59–86 °F, 15–30 °C) and in a dry place. The expiry date of the HemoCue Hb Microcuvettes in a sealed vial is printed on the vial. Once the seal is broken, the microcuvettes are stable for three months. Always keep the vial properly closed. Storage of the individually packaged cuvettes
The microcuvettes are to be stored at room temperature (59–86 °F, 15–30 °C) and in a dry place. The individual packaged microcuvettes are stable until the expiry date printed on each package.
Intended Use Quantitative determination of hemoglobin in capillary, venous or arterial blood. The HemoCue Hb 201+ system is used for quantitative determination of hemoglobin in whole blood using a specially designed analyzer, the HemoCue Hb 201+ Analyzer, and specially designed microcuvettes, the HemoCue Hb 201 Microcuvettes. HemoCue Hb 201 Microcuvettes are for In Vitro Diagnostic use only. The HemoCue Hb 201+ Analyzer is only to be used with HemoCue Hb 201 Microcuvettes.
HemoCue Hb 201+ Analyzer The analyzer can be stored and transported at 32–122 °F (0–50 °C). Operating temperature is 59–86 °F (15–30 °C). Allow the analyzer to reach ambient temperature before use. The analyzer should not be stored at high (i.e. > 90 % non-condensing) humidity. Specimen collection and preparation Capillary, venous or arterial blood may be used. Appropriate anticoagulants (e.g. EDTA or heparin) may be used, preferably in solid form to avoid dilutional effects. Mix all specimen tubes thoroughly on a mechanical mixer for at least 2 minutes or invert the tube 8–10 times by hand. Hemoglobin remains unchanged for days, provided that the blood does not become infected. If the specimen has been stored in a refrigerator, it will be viscid and the blood should be allowed to warm up to room temperature before mixing2. In case of peripheral circulatory failure, hemoglobin measurements from capillary sampling may be misleading. Confirmation of an unacceptable or unexpected laboratory result is considered as a
Theory The reaction in the microcuvette is a modified azidemethemoglobin reaction. The erythrocyte membranes are disintegrated by sodium deoxycholate, releasing the hemoglobin. Sodium nitrite converts the hemoglobin iron from the ferrous to the ferric state to form methemoglobin, which then combines with azide to form azidemethemoglobin. Storage and handling Operating temperature for the system is 59-86 °F (15-30 °C). The system should not be operated at high (i.e >90% non-condensing)

common, well established routine in the laboratory. Extra cellular fluid present in capillary samples due to individual physiology or the affects of unacceptable capillary sampling technique can cause false hemoglobin results. One of several pre analytical factors associated with technique revolves around the size and action mode of the lancet and how it is used. This and other factors associated with capillary sampling technique can have an impact on the puncture, blood flow and ultimately on the results obtained. Additional factors unrelated to sampling technique, such as an individual’s capillary circulation status, must also be recognized as potential causes of false results. Therefore when testing for hemoglobin using capillary blood as the sample, confirmation of an unacceptable or unexpected result is needed to rule out potential pre analytical factors as the cause. This is particularly helpful when a cut off value is used, i.e. when screening for nutritional status based on hemoglobin. Since the individual performing the test may not always be aware of all the potential pre analytical factors or even those that are directly or indirectly associated with sampling techniques, a second finger stick should be performed when wanting to rule out pre analytical factors as a cause of an unacceptable or unexpected result. Performance of the second finger stick by a different individual may aid in lessening the affect of the factors that could have been technique related. Always handle blood specimens with care, as they might be infectious. Consult local environmental authorities for proper disposal. Always wear protective gloves when handling blood specimens. The microcuvette is for single use only.
• Pipette or other transfer device (for venous, arterial or control material samples) • Lint-free wipe (non-fraying) • Hydrophobic surface (for venous, arterial or control material samples) Quality Control The HemoCue Hb 201+ Analyzer has an internal quality control, the “selftest”. Every time the analyzer is turned on, it will automatically verify the performance of the optronic unit of the analyzer. This test is performed every second hour if the analyzer remains switched on. Upon passing the SELFTEST, the display will show the HemoCue symbol and three flashing dashes, indicating that the analyzer is ready to perform a measurement. An error code will be displayed if the SELFTEST fails. Follow local guidelines regarding quality control procedures. If a quality control test is required by local or other regulations and therefore should be performed, only use controls recommended by HemoCue, see relevant package insert for more information. Expected values2
Adult Males 13.0–17.0 g/dL (130 – 170 g/L, 8.1–10.5 mmol/L) Adult Females 12.0–15.0 g/dL (120–150 g/L, 7.4–9.3 mmol/L) Infants, after neonatal period 11.0–14.0 g/dL (110–140 g/L, 6.8–8.7 mmol/L) Children, two years to teenage: gradual increase to adult normals. Due to a wide range of conditions (dietary, geographical, etc) which affect normal values, it is recommended that each laboratory establish its own normal range.

Measuring range 0 – 25.6 g/dL (0 – 256 g/L, 0–15.9 mmol/L). Results above 25.6 g/dL (256 g/L, 15.9 mmol/L) will be displayed as HHH. Values above 23.5 g/dL (235 g/L, 14.6 mmol/L) must be confirmed using a suitable laboratory method.
Signal input and signal output Accessory equipment to the analog and digital interfaces must be certified according to the respective UL standards (i.e. UL 60950-1 for data processing equipment and IEC 60601-1 for medical equipment). Furthermore all configurations shall comply with the system standard IEC 60601-1-1. Connections of additional equipment to the signal input or signal output connections is deemed to be “configuring a medical system”, and therefore assumes responsibility for the systems compliance within the requirements of IEC 60601-1-1. If in doubt, contact HemoCue AB.
