Claim Text:
1. A method for determining concentrations of lipids and at least one further substance in a body fluid sample, comprising the steps of: a) irradiating light through the body fluid sample at a multiplicity of wavelengths; and b) capturing a multiplicity of measured values of an absorbance of the body fluid sample at the multiplicity of wavelengths; characterized by the steps of: c) capturing a first measured value at a first wavelength at which an absorbance not caused by lipids is disregarded, and determining the concentration of the lipids by dividing the first measured value by an extinction coefficient specific for lipids; d) calculating a power-function approximation curve of the form for an absorbance of the lipids based on the first measured value by determining the factor p at predetermined exponent q; and e) determining a first approximate value of the concentration of a second substance based on a second measured value and a value of the approximation curve at a second wavelength.
