Großes Blutbild (Complete Blood Count)

A full haematological analysis measuring red blood cells, white blood cells with five-part differential, haemoglobin, haematocrit, MCV, MCH, MCHC, and platelet count. The großes Blutbild extends the basic blood count by breaking white blood cells into neutrophils, lymphocytes, monocytes, eosinophils, and basophils — essential for identifying infection patterns, allergic responses, and haematological abnormalities.

The complete blood count is the single most informative baseline blood test in clinical medicine. It quantifies every major cellular component of blood: red cell parameters reveal anaemia and its likely cause through indices like MCV and MCH, while haemoglobin and haematocrit directly measure oxygen-carrying capacity. Platelet counts flag bleeding risks or thrombocytosis before symptoms manifest. What distinguishes the großes Blutbild from the kleines Blutbild is the five-part white blood cell differential. Rather than simply counting total leucocytes, the analyser separates them into neutrophils (bacterial infection response), lymphocytes (viral immunity and chronic inflammation), monocytes (tissue repair and chronic disease), eosinophils (allergy and parasitic infection), and basophils (hypersensitivity reactions). Shifts in these ratios often provide the first laboratory evidence of an underlying condition weeks before other markers become abnormal. At SYNLAB München Zentrum, the analysis runs on automated haematology analysers with manual microscopic review triggered when flagged values fall outside reference intervals. Results are typically available within one working day. This test requires no fasting and is suitable as a standalone screening or as part of a broader diagnostic workup.
