Hemoglobinometer 📖 Wikipedia

A hemoglobinometer or haemoglobinometer (British English) is a medical device used to measure hemoglobin concentration in blood.^[4] It can operate by spectrophotometric measurement of hemoglobin concentration. Portable hemoglobinometers provide easy and convenient measurement of hematological variables, especially in areas where clinic laboratories are unavailable.^[5]

As per guidelines of National AIDS Control Organisation (NACO) for accurate results & mass screening,^{[citation needed]} analysis using hemoglobinometer is a recommended method used for absorbance measurement of whole blood at Hb/HbO2/Isobestic point,^{[citation needed]} based on microcuvette technology such as HemoCue 301^[6] and Mokshit-Chanda-AM005A.^[7]

Devices

edit

Hemoglobinometry that compares a blood sample to a color chart, in use circa 1850 - 1950
A hemoglobinometer made by the American Optical Company. The light of a battery-driven lamp is travelling on two paths to the eyepiece. One path goes through the blood sample, the other one through an adjustable filter. When the brightness of the two paths is equal, the hemoglobin level can be read on the device. Such devices were made in the 1940s.
