This technique employs a separation method based on the selective precipitation of apoprotein-B-containing lipoproteins (VLDL, LDL and (a)Lpa) by the action of phosphotungstic acid/Cl2Mg, sedimentation of the precipitate by centrifugation and subsequent enzymatic analysis as residual cholesterol from the high-density lipoproteins (HDL) contained in the clear supernatant.

The Fe(II) of all forms of haemoglobin, with the exception of sulphohaemoglobin, is oxidised by ferrocyanide to Fe(III) to methaemoglobin, which in turn reacts with ionised cyanide (CN-) to form cyanmethaemoglobin, a very stable derivative that absorbs at 540 nm. The intensity of the colour formed is proportional to the concentration of total haemoglobin in the sample.
