BACKGROUND The complete blood count parameters included in the present study are: Haemoglobin, Red cell count, Haematocrit, Mean corpuscular volume, Mean corpuscular Haemoglobin, Mean corpuscular haemoglobin concentration, Red cell distribution width, White blood cell count, Platelets, Lymphocytes, Neutrophils, Mid cells (Eosinophils, Basophils, Monocytes).a full blood count is one of the most frequently requested for investigations in the assessment of health status of an individual. Because it is simple, cheap, fast to obtain and is a reliable indicator of health. Abnormally high or low counts may indicate the presence of many forms of disease and hence the blood counts can provide an overview of an individual general health status. MATERIALS AND METHODS Complete blood count is performed by an automated analyser. All blood counts include a CBC count and leukocyte differential count, but modern analysers provide much more in addition. The blood is well mixed and placed on a rack in the analyser. This instrument has flow cells, photometers and apertures that analyse different elements in the blood. The cell counting component counts the numbers and types of different cells within the blood. The reports are printed out or sent to the computer for review. The study was conducted at five private hospitals in Kurnool. Babies delivered in five private hospitals affiliated to our hospital for neonatal services attended by DNB resident, Kurnool, Andhra Pradesh. 900 cord blood samples of healthy newborns (full term newborns of which 477 are male children and 423 are female children), who are included in the inclusion criteria, in the duration period of study period of 1 year from May 2013- April 2014. RESULTS Comparison of various red cell parameters and white blood parameters in cord blood of newborns between Vaginal and caesarean section, male and female neonates is given below. CONCLUSION Full blood counts parametres from neonatal cord blood are summarized as follows: The mean haemoglobin level is 14.99 ± 1.63 g/dl, Mean Haematocrit value is 46.8 ± 8.04%, mean MCV is 101.09 ± 6.12 fl, mean RDW is 13.1 ± 1.75%, mean WBC is 7.56 ± 2.19*10, mean neutrophils count is 54.83 ± 9.56%, a mean lymphocytes count is 40.22 ± 6.52, mean MID value is 6.70 ± 2.38% and a mean platelet count is 271.64 ± 76.1*1000.
