Γ 100
Where the RBC is expressed in 10

/L, MCV in fL and HGB in g/L.
RDW-CV:
Based on the RBC histogram, the analyzer calculates the CV (Coefficient of Variation) of the
erythrocyte distribution width, expressed in %.
RDW-SV:
Based on the RBC histogram, the analyzer calculates the SV (Standard Deviation) of the
erythrocyte distribution width, expressed in fL.
3.4.4 Derivation of PLT - related parameters
MPV:
Based on the PLT histogram, the analyzer calculates the mean platelet volume and expresses
the result in fL.
PDW:
Based on the PLT histogram, the analyzer calculates the platelet distribution width which is
reported as 10 geometric standard deviation (10 GSD).
PCT:
The analyzer calculates the PCT (%) as follows:
ππΆπ =
ππΏπ Γ πππ
10000
Where the PLT is expressed in 10

/L and MPV in fL.
P-LCR:
Based on the PLT histogram, the analyzer calculates the platelet large cell ratio and expresses
the result in %.
P-LCC:
The analyzer calculates the P-LCC (10
9
/L) as follows:
ππΏπΆπΆ = ππΏπ Γ ππΏπΆπ
Where the PLT is expressed in 10
9
/L and P-LCR in %.
IPF:
Based on the PLT-O scattergram, the analyzer calculates the immature platelet fraction and
expresses the result in %.
