A well plate (1) for holding samples of a bodily fluid during analysis thereof, typically in an analytical apparatus, includes a plate (2) having a plurality of first wells (3) extending downwardly therefrom for holding a sample during optical analysis of the sample, and a plurality of second wells (4) for holding samples during mechanical analysis of the samples. A plurality of holding wells (8) are provided for initially receiving and holding samples of the bodily fluid to be analysed so that samples of relatively accurate size can be pipetted from the holding wells (8) to the first and second wells (3,4).
