SERUM SAMPLE QUALITY DETERMINATION

摘要

A method and device for measuring HIL levels in blood serum samples that are disposed in an automated, clinical chemistry analyzer. The device probe can be attached adjacent to a pipette or sample probe of the analyzer and includes fiber optic bundles and a light-reflecting surface. A cutaway portion is provided between the ends of each of the fiber optic bundles and the light-reflecting surface. One of the four fiber optic bundles is optically coupled to a light-emitting source. Each of the other three fiber optic bundles collects and filters reflected light from the reflecting surface. The light filters correspond to the optimal absorption wavelengths for one of hemoglobin, bilirubin, and triglycerides. A light intensity-measuring device is optically coupled to each of the three fiber optic bundles, to measure the intensity of the filtered, reflected light. A processing device receives output data signal from the light intensity-measuring devices; stores the data; and calculates whether a serum sample has elevated levels of one or more of HIL.

主权项

1. A serum screening device for use with an automated, clinical chemistry analyzer, the device comprising:
a plurality of fiber optic bundles, each having an exposed end; a light-reflecting surface that is disposed at a distal end of the device; a support element for supporting the plurality of fiber optic bundles and the light-reflecting surface; and a cutaway portion disposed between the light-reflecting surface and the ends of the plurality of fiber optic bundles, and wherein a first fiber optic bundle of the plurality of fiber optic bundles is optically coupled to a light-emitting source that is adapted to emit light from the end of the first fiber optic bundle, through the cutaway portion, towards the light-reflecting surface, and wherein each of the other fiber optic bundles of the plurality of fiber optic bundles includes:
a light filter; anda light intensity-measuring device that is adapted to measure an intensity of reflected light.
