How to fix HemoCue Test Equipment with no characters on the display?
If there are no characters on the display, it could be due to: * Power not being received: Ensure the power adapter is properly connected. * Depleted batteries: Replace the batteries with six new type AA batteries. If the issue persists after checking these, the display may be out of order.
What to do if HemoCue Test Equipment measurement on control materials are out of range?
If control material measurements are out of range, this may be due to several reasons: * Improper sampling technique: Use a new microcuvette and repeat the measurement. * Expired or improperly stored microcuvettes: Check the expiration date and storage conditions. * Expired or improperly stored control material: Verify the expiration date and storage conditions. * Improperly mixed or not at room temperature control material: Ensure the control material is mixed properly and at room temperature. * Unsuitable control material: Only use controls recommended by HemoCue.
Why are HemoCue Test Equipment measurements on patient samples higher or lower than anticipated?
Inaccurate measurements on patient samples may occur due to improper sampling technique. To resolve this, take a new microcuvette and repeat the measurement. Also, check the expiration date and storage conditions of the microcuvettes, as expired, damaged, or improperly stored microcuvettes can affect results.
What does WbC mean on HemoCue Measuring Instruments?
To address the 'WbC' message on your HemoCue device, take a microcuvette and perform the measurement.
Why is the HemoCue Measuring Instruments cuvette holder not moving correctly?
If the cuvette holder is not moving into the correct position, it suggests that the magnet in the cuvette holder is missing. The analyzer requires service; please contact your local distributor.
Why doesn't the HemoCue Measuring Instruments display switch to ready for measuring?
If the HemoCue Measuring Instruments display does not switch from “?” and “WbC” to three flashing dashes, it indicates that the cuvette holder sensor is out of order. The analyzer needs service; contact your local distributor.
How to fix Err35 on HemoCue Measuring Instruments?
To resolve Err35 on your HemoCue analyzer: a. Turn off the analyzer. b. Replace the batteries with six new AA batteries. c. Alternatively, use the power adapter.
Why is the HemoCue Measuring Instruments display showing erroneous characters?
Erroneous characters on the display may indicate: 1. The display is out of order. 2. The microprocessor is out of order. In both cases, the analyzer requires servicing. Contact your local distributor.
What does LLL mean on HemoCue Measuring Instruments?
The 'LLL' message on the HemoCue Measuring Instruments indicates that: 1. The measured value is below 0.3 x109/L (300/mm3, 300/µL). Results exceeding the LLL limit should be verified with a suitable laboratory method and be questioned as to the pathological condition of the patient. 2. The microcuvette is empty or not filled with sample. Use a new microcuvette, repeat the measurement, and ensure the microcuvette is adequately filled.
What causes out-of-range measurements on control materials with HemoCue Measuring Instruments?
If your control material measurements are consistently high or low, consider these possibilities: 1. Improper sampling technique. Use a new microcuvette and repeat the measurement. 2. Expired, damaged, or poorly stored microcuvettes. Check their expiration date and storage conditions. 3. Expired or improperly stored control material. Verify the expiration date and storage conditions. 4. Control material not properly mixed or not at room temperature. Ensure it’s mixed well and at the correct temperature. 5. The control material might not be suitable for the HemoCue WBC system.
