Title (EN) APPARATUS AND METHOD FOR RAPID SPECTROPHOTOMETRIC PRE-TEST SCREEN OF SPECIMEN FOR A BLOOD ANALYZER
(FR) APPAREIL ET PROCEDE DE TRIAGE SPECTROPHOTOMETRIQUE AVANT TEST DE PRELEVEMENTS DESTINES A UN ANALYSEUR DE SANG
Abstract:
(EN) A method and apparatus for use in respect of samples which are assessed for quality prior to testing in a clinical analyzer. The method and apparatus identify parameters such as gel level and height of fluid above the gel in blood samples, where appropriate, for the purposes of positioning the specimen for determination of interferents. Such interferents include hemoglobin (Hb), total bilirubin and lipids. These interferents are determined by measurement of absorption of different wavelengths of light in serum or plasma, or other specimens, which are then compared with values obtained through calibration using reference measurements for the respective interferents in serum or plasma or other type of specimen. Determinations of temperature of the specimen, as well as specimen type, for example whether the specimen is urine or plasma or serum, may also be carried out.
(FR) Cette invention concerne un procédé, et un appareil associé, permettant d'évaluer la qualité d'échantillons avant test dans un analyseur clinique. Ledit procédé, associé audit appareil, permet d'identifier des paramètres tels que le niveau de gel et la hauteur de fluide au-dessus du gel dans des échantillons sanguins, lorsque cela est nécessaire, dans le but de positionner le prélèvement en vue de la détermination des agents parasites. De tels agents parasites incluent l'hémoglobine (Hb), la bilirubine totale et les lipides. On détermine ces agents parasites en mesurant l'absorption de rayonnements de longueurs d'ondes différentes dans du sérum et du plasma, ou autres prélèvements, que l'on compare à des valeurs obtenues par étalonnage en utilisant des mesures de référence pour ces agents parasites respectifs présents dans le sérum et le plasma ou autre type de prélèvement. On peut également évaluer la température du prélèvement, de même que le type du prélèvement, et par exemple évaluer si le prélèvement est de l'urine, du plasma ou du sérum.
