Hemo Control Hemoglobin Analyzer

Hemo Control's measuring method is azide methemoglobin. The reference method that  Hemo Control is calibrated against is the cyanmethemoglobin reference method, known as NCCLS (now CLSI) reference method. This methodology yields results comparable with ICSH standards. A maximum tolerance of 0.3 g/dL (3 g/L or 0.2 mmol/L) at 15.0 g/dL (150 g/L or 9.3 mmol/L) is accepted.

Hemo Control (REF 3040-0010-0218) can be upgraded to use its on-board data management (DM) functions if, for example, a setting wishes to implement a LIS solution. The bi-directional interface simplifies the connection to LIS solutions using a public standard protocol (LIS2-A2). Connection to a LIS is subject to an adaptation of the local installation or middleware to use Hemo Control's interface. EKF Diagnostics provides support to connect to specific LIS solutions.

A USB connector cable or a serial Sub-D-9 cable can be used to establish the PC connection. Alternative connection solutions can be realized using serial-to-LAN or BT-to-LAN bridges.

Hemo Connect software allows the configuration of DM enabled Hemo Control analyzers to export data in a standard file format. Meanwhile, Hemo Connect light (a freeware version) supports data export only. 

Note: The Hemo Control Manager device already supports data management function at delivery. Additionally, the device features a Bluetooth interface for data communication.

Data management functions include: Barcode identification of patients, access control and identification of operators, recognition of cuvette LOT and control materials, definition of Quality Control scheme and QC lockout function, addition of comments to test results, flagging of rejected values and range violations.

Barcodes are read by the analyzer using an ergonomic hand-held scanner.

Unlike other brands, Hemo Control has three methods for quality control. Operators may choose the suitable control methods based on their local QC requirements.

1. Each time the analyzer is turned on a self-test is performed automatically.
2. A control cuvette is included with each analyzer. Using the control cuvette is not compulsory but we do recommend its' use as a visible quality control method.
3. Liquid quality controls (Hb-con) are also available. 

EKF recommends that the optics of the analyzer are cleaned at least once each month. Depending on usage and sample through-put more frequent cleaning may be required.

Only the Hemo Control Cleaner should be used for cleaning the optics. To do this the cuvette holder must be removed from the instrument. The cuvette holder should also be cleaned with a cleaning solution or an aqueous disinfectant solution.
