Given the following information, Calculate the number of RBCs and WBCs in the CSF cell count: RBCs counted on side 1: 76 RBCs counted on side 2: 82 WBCs counted on side 1: 112 WBCs counted on side 2:100 # of squares counted on each side: 4 1:100 dilution RBCs / uL = WBCs / uL =
- Given the following information, Calculate the number of RBCs and WBCs in the CSF cell count:
- RBCs counted on side 1: 76
- RBCs counted on side 2: 82
- WBCs counted on side 1: 112
- WBCs counted on side 2:100
- # of squares counted on each side: 4
- 1:100 dilution
RBCs / uL =
WBCs / uL =
To determine the number of RBCs per microliter (μL) in the cerebrospinal fluid (CSF) cell count, follow these steps:
1: Calculate the average number of RBCs per side.
To find the average RBC count per side, add the RBC counts from side 1 and side 2 and divide by 2:
Average RBCs per side = (RBCs counted on side 1 + RBCs counted on side 2) / 2 Average RBCs per side = (76 + 82) / 2 = 158 / 2 = 79 RBCs per side
2: Calculate the total RBC count per μL for one side.
Now, we need to determine the RBC count per μL for one side. To do this, divide the average RBC count per side by the number of squares counted on one side (4) and then multiply by the dilution factor (1:100):
RBCs per μL (one side) = (Average RBCs per side / Squares counted on one side) * Dilution factor RBCs per μL (one side) = (79 / 4) * 100 = 1975 RBCs/μL (one side)
3: Calculate the total RBC count per μL for both sides.
Since we've calculated the RBC count per μL for one side, to find the total RBC count per μL, simply add the values for both sides:
Total RBCs per μL (both sides) = RBCs per μL (one side) + RBCs per μL (one side) Total RBCs per μL (both sides) = 1975 RBCs/μL + 1975 RBCs/μL = 3950 RBCs/μL
