HemoCue
Product Description
The HemoCue WBC DIFF System measures white blood cell (WBC) count including a five-part differential at the point of care in order to rapidly provide information about the state of the immune system to medical professionals.

Design Specifications
A drop of blood is put into the Hemocue system and within 5 minutes, information about immune cell count is displayed. This video (1) shows a step-by-step use of the product.

Replacement consumables can be purchased from contacting HemoCue on their website. Additional websites, such as Wilburn Medical, also carry the replacement consumables.
Lifecycle
5 - 10 years
Manufacturer Specified Performance Parameters
The manufacturer specifies a detection range of 300-30000 cells/µL, with a sample volume of 10uL, and a measurement time of less than 5 minutes.
Vetted Performance Status
In the independent study by Hammersmith Hospital, the device provided reliable comparability in the range of 0.4–30.0 × 109/l. This is slightly narrower than the range of 0.3–35 × 109/l specified by the manufacturer; however, samples with WBC < 0.4 × 109/l were flagged as low (code LLL) and conversely, those with counts above 30.0 × 109/l were flagged as high (code HHH); thus, in a clinical setting, this flagging would provide adequately reliable information.
Safety
Unreliably measuring immune function could provide incorrect information to doctors, leading to incorrect diagnosis and treatment.

The main material is polyethylene, which is cheap, but has a short lifetime. It is only the fittings that are of PVC. A 40 m3 system provides enough gas to run a small engine for a few hours a day to generate electrcity, as long as there is sufficient feed material, usually cattle dung. The performance figures seem reasonable.

Jeremy Schonhorn says:
The Hemocue WBC Diff system is a vetted technology to determine white blood cell count (neutrophils, lymphocytes, monocytes, eosinophils and basophils). Although the device is powered with batteries, they are increasingly accessible in remote locations and should not be considered a limitation to usability and portability.
The technology is accessible and ability to profile blood at the point of care from finger stick whole blood will enable physicians and health care providers to assess patient health (e.g. trauma, infection).
Two fields in the performance parameter table for this kind of products: “ICT technology platform” is not appropriate (Maximum current and Maximum power)
The firmware that Angaza provides should be in terms of quality of service. Two suggestion would be additional cost to products, bandwidth requirement and training/technical support.
Checking the ICT only field, the performance parameters make more sense for Angaza and Lumeter: User coverage, service needed, etc.
