Claim:
1. A method for determining the concentration of lipids in a body fluid sample, comprising the steps: a) transirradiating the body fluid sample with light at a multiplicity of wavelengths; b) capturing a first measurement value (A1) at a first wavelength at which the absorbance not caused by lipids is negligible; c) capturing a second measurement value (A2) at a second wavelength at which bilirubin has an absorbance maximum; d) capturing a third measurement value (A3) at a third wavelength at which hemoglobin has an absorbance maximum; e) capturing a fourth measurement value (A4) at a fourth wavelength at which the absorbance not caused by bilirubin and hemoglobin and lipids is negligible; f) calculating a power-function approximation curve (L g) determining an approximation value of the bilirubin concentration (c h) determining an approximation value of the hemoglobin concentration (c i) determining a third theoretical absorbance value (E j) ascertaining a deviation of the third theoretical absorbance value (E wherein: I.—if the deviation ascertained in step j) does not exceed a predetermined threshold value—the concentration (c II.—if the deviation ascertained in step j) exceeds a predetermined threshold value—a corrected approximation curve (L
