Morfologia — Complete Blood Count

Full blood count (morfologia) with automated differential measuring red blood cells, white blood cells, haemoglobin, haematocrit, platelets, and white cell subtypes. The most fundamental screening test in laboratory medicine. At 16 PLN (~3.70 EUR) plus 5 PLN collection fee, this is among the cheapest CBCs available in Poland and a fraction of what German labs charge for the identical assay.

The complete blood count is the single most frequently ordered laboratory test in clinical medicine, providing a broad snapshot of haematological health from a single venous sample. The test quantifies red blood cell count, haemoglobin concentration, haematocrit (packed cell volume), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), and red cell distribution width (RDW). These parameters together classify anaemias by morphology: iron-deficiency anaemia presents with low MCV (microcytic), while B12 or folate deficiency produces elevated MCV (macrocytic). Chronic disease anaemia is typically normocytic with normal MCV. The white blood cell count with automated five-part differential breaks down neutrophils, lymphocytes, monocytes, eosinophils, and basophils as both absolute counts and percentages. Neutrophilia is the hallmark of bacterial infection; lymphocytosis suggests viral illness or chronic lymphoproliferative disorders; eosinophilia raises suspicion of parasitic infection, allergic disease, or drug reaction. The platelet count screens for bleeding risk (thrombocytopenia) or clotting tendency (thrombocytosis). At InterLab, the CBC costs 16 PLN — roughly 30-40% less than the same test at Synevo or Diagnostyka in Poznan. A 5 PLN per-visit collection fee applies regardless of how many tests are drawn. Results are typically available within 24 hours. For visitors from Berlin, where a private-lab CBC costs 15-25 EUR, the price differential makes a day trip to Poznan economically worthwhile when combining multiple tests.
