<p>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.</p> |
