Screening of beta thalassaemia Trait using red cells indices and red cell count
. Pak J Pathol 2008; 19(4): 129-33.
RBC: Red cell count
WBC: White blood cell MCV: Mean cell volume MCH: Mean cell haemoglobin MCHC: Mean cell haemoglobin concentration RDW: Red cell distribution width.
The samples were put into EDTA-containing vacutainer tubes and transported without delay to Komfo Anokye Teaching Hospital and refrigerated at 4[degrees]C until analysed for full blood count, haemoglobin (Hb), packed cell volume (PCV)/haematocrit, mean corpuscular volume (MCV), red cell count
(RBC), and platelets using the Cell-Dyn 3700 Haematology Analyzer (Abbott Diagnostics) and also for fasting blood glucose.
Detailed consideration of sex-specific differences shows that these can be observed after the onset of puberty, but not before, in many analytes (alkaline phosphatase, ALT, AST, [gamma]-GT, LDH, hematocrit, hemoglobin, red cell count
Care must be taken when interpreting reticulocyte count results because the percentage reticulocyte count should always be interpreted in conjunction with the haemoglobin levels and red cell count
and the nature of blood sample whether capillary or venous.18,19
Red cell levels during this induced remission of PV by phlebotomy alone gradually rise and remain at erythrocythemic levels above 6x[10.sup.12]/L, and so the red cell count
as an index of therapy is of little value.
"In addition the red cell count
rose from 66 per cent to 73 per cent between those two days, once again proving that she had been given the four units of blood.
Forty one children diagnosed with iron deficiency anemia on the basis of hemoglobin, red cell count
, red cell indices including MCV, MCH, MCHC and RDW, red cell morphology and serum iron levels were included.
As presented in Table 1; hemoglobin (Hb), packed cell volume (PCV) and red cell count
were significantly lower in G-6-PD deficient subjects than in the non-deficient (control) group, (p<0.05).

--Preliminary differential blood analysis on days 21-23 showed an increase in red cell count
, the hemoglobin and hematocrit levels and the total number of myeloid cells in the surviving animals treated with PLX cells.
