The blood count without differential test comprises the determination of the number of erythrocytes, leucocytes and thrombocytes, of haemoglobin, haematocrit and different indices such as MCV and MCH.
With the complete blood count, the leucocytes are additionally differentiated according to neutrophilic, eosinophile and basophile granulocytes as well as lymphocytes and monocytes.
For reasons of greater accuracy, the counting is carried out by a machine. If abnormalities are detected during the automatic analysis, a microscopic examination of the smear will be carried out in addition. A manual smear examination for microscopic differentiation can also be requested separately, especially if there is a specific suspicion of a haematological disease.
With asymptomatic patients (e.g. check patients), a blood count leads to a new diagnosis in no more than one in every 200 cases. Therefore, it is frequently a subject of discussion in literature and at congresses whether this blood screening is indicated at all with symptomatic patients.
Blood count without differential:
Differential blood count:
Erythrocytes can be assessed according to the cell size, cell colour and cell shape. Different erythrocyte shapes can indicate diseases or support or confirm tentative diagnoses, e.g. spherocytes as an indication of hereditary spherocytosis (spherocytic anaemia); fragmented red blood cells (schistocytes) are helmet-like or eggshell-like erythrocyte fragments as a possible indication of a mechanical destruction of erythrocytes, e.g. after cardiac valve replacement or haemolytic-uraemic syndrome (HUS). Erythrocytes with basophilic stippling (precipitated ribosomal RNA) are signs of a disturbed regeneration of erythropoiesis (e.g. saturnine poisoning).
