Abstract: The method comprises arranging a plurality of test devices in a holder, and loading, to at least one of the test devices, a sample of a physiological liquid. The at least one parameter of the sample loaded to the at least one test device is then determined, the at least one test device being retained in the holder after the determination. The holder with the at least one test device retained therein is then discarded in such a manner that the at least one test device is substantially separated from the ambience, thus reducing the risk of contact between an operator and sample loaded to the at least one test device.

Abstract: The method is a method of photometric in vitro determination of the content of an analyte in a sample of whole blood. The blood sample is transferred from an in vivo locality directly to the sample container of a sampling device. The sample container comprises a measuring chamber wherein there is provided a transparent body the radiation transmission characteristics of which vary with the content of analyte in the environment of the body. The transparent body is equilibrated with the sample and thereafter the measuring chamber is deformed in a controlled manner while the portion of the measuring chamber located in the radiation transmission path is drained for blood sample. The analyte content is determined on the basis of detection of the radiation transmitted from the radiation source through the deformed measuring chamber and the transparent body and to the radiation detector. A sampling device and an analyzer for use in photometric in vitro determination of the content of an analyte in a blood sample is also described.

Abstract: The method is a method of photometric in vitro determination of a blood gas parameter in a blood sample. The blood sample is transferred directly from an in vivo locality to an at least partially transparent sample container, whereafter the connection between the sample containing sample container and the blood circulation is broken. Subsequently the sample container with its content of blood sample is brought into optical communication with an optical system comprising a radiation source and a radiation detector interacting therewith, preferably by placing the sample container in a sample container system in an analyzer. The blood gas parameter is determined on the basis of the radiation detected by the radiation detector. A system for photometric in vitro determination of a blood gas parameter in a blood sample is also described.

Abstract: The method according to the invention is a method of photometric in vitro determination of the content of oxygen in a blood sample. The blood sample is transferred directly from an in vivo locality to an at least partially transparent sample container of a sampling device. The sample container has a measuring chamber wherein a luminophor is provided, whereof the luminescence is quenched in the presence of oxygen. The oxygen content is determined on the basis of the radiation detected by the radiation detector. A sampling device and a system for photometric in vitro determination of oxygen in a blood sample is also described.
