The HemoCue Hb 201+ system is a portable device for measuring hemoglobin levels in the blood, compatible with capillary, venous, or arterial samples. It provides laboratory-quality results in less than a minute, with high precision, designed for healthcare centers, clinics, field screening, or mobile units.
| Feature | Detail |
| Measurement principle | Modified azidomethemoglobin reaction with turbidity compensation; dual-wavelength (570 nm for hemoglobin + 880 nm for turbidity correction). |
| Calibration | Factory calibrated according to the HiCN / ICSH reference method. No further calibration is required between microcuvette batches. |
| Sample volume | ~10 µL of whole blood (capillary, venous, or arterial) |
| Measurement range | 0.5 to 25.6 g/dL (i.e., 5 to 256 g/L or 0.3 to 15.9 mmol/L) |
| Measurement time | Between 15 and 60 seconds, depending on the hemoglobin concentration |
| Memory / storage | Records date/time for up to 600 results directly on the device |
| Power supply | AC adapter or 4 AA batteries |
| Operating temperatures | Approximately 15-30 °C for normal usage |
| Storage temperatures | Device: 0-50 °C; Unopened microcuvettes: 15-30 °C; stable for 3 months after opening the vial |
| Dimensions | Approx. 160 × 85 × 43 mm |
| Weight | Approx. 350 g (with batteries installed) |
| Interface & communication | Printer connectivity option; data transfer via "Basic Connect" interface; optional barcode reader; Bluetooth accessories available. |
| Quality control | Built-in self-test; optional liquid controls for periodic verification |
Results can be affected by factors such as extreme hematocrit, severe turbidity, or blood alterations (e.g., lipemia, high leukocytosis), although the device actively compensates for standard turbidity.
