Hematopathologie
1 Drie pijlers van hematologisch onderzoek
Perifeer bloedonderzoek (PBO)
1.1.1 Verschillende cellen
Referentiewaarden Levensduur Teveel Tekort

Erytrocyten 4,4-5,8 . 106/µl 120 dagen Erytrocytose Anemie
= RBC 6
4,0-5,3 . 10 /µl
Leukocyten 5000-10 000/µl 1-2 dagen Leukocytose Leukopenie
= WBC (bij infectie)
Trombocyten 200 000-400 000/µl 5-10 dagen Trombocytose Trombopenie
=T
→ Meest RBC, dan T, minst WBC
→ Tekort aan alle 3 → patiënten met chemotherapie (door onderdrukking BM)
1.1.2 Parameters bloedanalyse
1.1.2.1 Hematocriet (Hct):
= verhouding RBC t.o.v. totale bloedvolume (belangrijk bij bepaling anemie)
▪ Bepaling: flowcytometer + berekening
▪ Referentiewaarden: 41-51 (45) % en 36-47 (42) %
▪ Heel stabiele waarde, wijziging door EPO-verandering
▪ Ongeveer Hct = Hb . 3
1.1.2.2 Hemoglobine (Hb):
= hoeveelheid zuurstof-dragend proteïne
▪ Bepaling: flowcytometer: RBC → Hb komt vrij → stof bindt er op
▪ Referentiewaarden: 12-15 g/dL
1.1.2.3 Mean Cell Volume (MCV):
= de gemiddelde grootte van RBC
𝐻𝑐𝑡
▪ Bepaling: #𝑅𝐵𝐶 . 1012/𝐿
▪ Referentiewaarden: 80-100 femtoliter (10-15)
▪ Classificatie: micro-/normo-/macrocytair
▪ Te hoge MCV-waarde komt door bloedarmoede ten gevolge van vit-B12 gebrek
▪ Te lage MCV-waarde komt door bloedarmoede ten gevolge van ijzegebrek
1.1.2.4 Mean Cell Hemoglobin (MCH)
= gemiddelde Hb-hoeveelheid in RBC
𝐻𝑏(𝑔/𝑑𝐿)
▪ Bepaling: #𝑅𝐵𝐶 . 1012/𝐿 . 10
▪ Referentiewaarden: 27-34 picogram (10-12)
1.1.2.5 Mean Cell Hemoglobin Concentration (MCHC)
= hemoglobine-concentratie in RBC rekening houdend met het volume van RBC
𝐻𝑏 𝑀𝐶𝐻
▪ Bepaling: of
𝐻𝑐𝑡 𝑀𝐶𝑉
▪ Referentiewaarden: 31-35 g/dL
▪ Classificatie: hypo-/normo-/hyperchroom (kleur wordt bepaald door Hb-conc)
1.1.2.6 Relative Distribution Width (RDW)
= variatie in grootte van RBC
▪ Bepaling: berekening
▪ Referentiewaarden: 11-16 %
▪ Bij sommige soorten bloedarmoede bestaat er een grote variatie in de afmetingen
van RBC → gestegen RDW
1.1.3 Terminologie bij bekijken bloeduitstrijkje
▪ Poikylocytose = afwijking in vorm
▪ Anisocytose = Afwijking in grootte (RDW)
▪ Polychromasie = afwijking in kleur (MCHC)
