The system consists of a reflectance meter and proprietary hemoglobin test cards that measures hemoglobin on a single drop of blood in seconds. Each package of reagent test cards includes a lot-specific quality control key. The system automatically pre-checks the test card when it is inserted into the meter. As soon as the drop of blood is added to the card, the sample is detected and the Hgb result is displayed on the LCD screen in either g/dL or mmol/L.
The STAT-Site MHgb specifications include a linear range of 6 to 21 g/dL, within-run precision CVs of 3.5 percent to 4.9 percent and total precision CVs of 2.9 percent to 4.2 percent. These results were based on whole blood samples from infants, children and adult patients.
ITC, Edison, N.J., manufactures the Hgb Pro Professional Hemoglobin Testing System, consisting of a compact, battery-operated meter and single-use test strips, used in measuring total hemoglobin, from capillary or venous whole blood. The system is portable, easy to use and provides a test result in 30 seconds or less. Testing entails placing a drop of venous or arterial blood on a test strip, which is then inserted in the test device. The Hgb Pro is self-calibrating. It includes data storage for the most recent 250 tests. Liquid quality controls are available and the company recommends that quality-control testing should be performed upon receipt of new lot of test strips and once every three months thereafter.
