Point-of-care whole blood analyzers designed to measure the concentration of glucose, cholesterol, and lipids usually in a capillary blood sample (e.g., from a fingerstick). These analyzers may use one or more technologies such as reflectance photometry (i.e., by measuring the amount of light that is reflected from reagent-impregnated test pads or reagent strips that have reacted with the blood sample) and/or electrochemical methods. Glucose/lipid profile analyzers are capable of determining the concentration of glucose, high-density lipoprotein (HDL) and total cholesterol, and triglycerides. Some other related values (e.g., low-density lipoprotein [LDL] cholesterol) may be obtained using the analyzer software. The results are shown in the analyzer display; some analyzers include a printer for immediate printing of the results. Point-of-care glucose and lipid profile analyzers are used at the bedside, in operating rooms, and emergency departments; some are also intended for home use by patients with diabetes and/or heart diseases.
