Abstract

An instrument (20) and a method for determining a characteristic of a sample of a biological fluid (blood) or a control includes a first source (64) providing radiation for transmission through a region of the sample and a second source (56, 58) providing heat for maintaining the sample at a desired temperature. The second source includes a plate (58) having first and second generally opposite sides. The plate (58) includes a material which is not opaque. The first source (64) is mounted (65) on the first side of the plate (58) and the sample is disposed on the second side of the plate (58) during the determination of the characteristic. The radiation passes through the non-opaque material and into the sample and is then detected in order to determine the characteristic.
