In RBC pipet, you dilute up to what mark?

The essential idea here is how the RBC counting pipette is standardized for dilution. You fill the pipette with blood up to the zero mark, then add diluting fluid to bring the liquid up to the 101 mark. Reaching the 101 mark creates a 1:101 dilution, which is the standard dilution factor used in this method for calculating RBC concentration. This specific endpoint ensures consistent results across samples; using other marks would produce different dilution factors and disrupt comparability.
