The present invention relates to a method of diagnosing an existing or developing acute pneumonia induced by a microorganism by detecting one or more volatile organic compound(s) in a subject's sample and the use of one or more volatile organic compound(s) for the detection oforand optionally opportunistic pathogen

Method of diagnosing pneumonia by detecting a volatile organic compound

A method for monitoring the use of a consumable in a disposable design in multiple analyzers is disclosed. The method provides a disposable consumable; uses the consumable as intended during operation of the first analyzer; and collects usage-relevant information for the consumable concerning the intended use of the consumable during operation of the first analyzer. Usage-relevant data derived from the usage-relevant information is stored in a memory unit assigned to the consumable. The consumable may be removed and again provided in the first or second analyzer. The first or second analyzer partially reads the usage-relevant data from the memory unit, evaluates the usage-relevant data, and derives control signals concerning the permissibility and/or type of a further intended use of the consumable during operation of the analyzer as a reaction to the evaluation of the read usage-relevant data.

A method and an apparatus for accelerating the equilibration of a fluid, typically the reference fluid of an analyzer, are provided, the surface of the fluid being in contact with a gas phase. The device can include a cassette, which can be exchangeably inserted into an analyzer and which holds at least one flexible, gas-tight bag, in which the fluid and the gas phase are accommodated. The cassette or the analyzer can include at least one transmitting element, which can be caused to vibrate and which mechanically contacts the flexible bag in order to input mechanical energy into the liquid in at least one wall region.

The invention relates to a method and device for measuring blood gas parameters, preferably pH, pCO, and pO, in a blood sample, where the blood sample of a patient is fed into at least one measuring cell of an analyzer. In order to obtain accurate values for the blood gas parameters even in cases where the temperature of the patient deviates from normal temperature, the temperature of the patient or blood sample is measured upon sample withdrawal, and the measured temperature is transmitted to the analyzer or is recorded by the analyzer, and the temperature of the measuring cell of the analyzer is adjusted to the measured temperature by cooling or heating.

The invention relates to a method for determining the current filling level of a liquid, preferably a calibrating, quality control, or cleaning fluid, or waste water, in a container, for example of an analyzer, where an immersion pipe is dipped into the liquid in the container to be filled or drained. The immersion pipe is connected to a pumping device via a tube system. The pressure p in the tube system is measured and increased, starting from the ambient pressure p, until a first discontinuous pressure change occurs at pressure pdue to the liquid column in the immersion pipe being forced out of the pipe, and/or the pressure p in the tube system is decreased until the liquid column in the immersion pipe reaches a change in cross-section of the immersion pipe, which change is situated above the maximum filling level of the liquid, such that a second discontinuous pressure change occurs at pressure pdue to the liquid column reaching the change in cross-section. The pressure difference between ambient pressure pand the pressure por pat one of the two pressure discontinuities or the time tor tuntil one of the two pressure discontinuities is reached, is recorded and used to determine the current filling level of the container.
