Objective This study was aimed to establish local reference values for hematological indices and hemoglobin (Hb) fractions in umbilical cord blood (UCB) for the northern population of Tunisia. Study Design Our study included full-term newborns by vaginal deliveries. Hematological parameters were collected using an automated blood cell counter. The amounts of Hb fractions were measured by capillary electrophoresis of Hb. Statistical analysis was performed using R software. Results A total of 328 cord blood samples were analyzed. Among them, 154 (male: 44.8%, female: 55.2%) were used to establish reference values. The normal reference values of complete blood count (CBC) and Hb fractions were calculated. Mean neonatal Hb was 14.75 ± 2.26 g/dL. Gestational age affects the expression of CBC values as red blood cell (RBC), Hb, hematocrit (Hct), mean corpuscular volume (MCV), white blood cell (WBC), and the Hb profile. Umbilical blood hemogram parameters and Hb profile are affected by the environment; higher in newborns from urban regions but not affected by gender ratio. Conclusion Reference ranges of normal CBC indices and Hb fractions have been successfully established in Tunisian neonates' UCB. Our data suggest reference values that could be useful for neonatal patients' laboratory results and clinical interpretation. Key Points

Aim: To establish the reference values of hematological parameters in blood donors of all the four provinces of Pakistan as a general population. Methods: This was a multicenter cross-sectional study conducted from Jan 2017-Oct 2017 in the blood bank and the Dept. of Haematology, The CH&ICH, Lahore, Fatimid Foundation, Karachi, Bolan medical college, Quetta, Armed Forces Institute of Transfusion, Rawalpindi & Ayub medical college, Abbottabad, KPK. Blood samples of 1060 male and female blood donors were collected from the blood banks of all the centers mentioned above. CBC and differential were performed using an automated hematology analyzer in the respective departments. Results: The mean and 95% reference values (2.5th-97.5th) for males WBC 7.752+4.506×109 cells/L, RBC 4.958 +1.331, HB 14.258 +3.423 g/dl, HCT 41.967 +16.345, MCV 84.584 +15.933, PLT 219.485 +197.331, LYM 3.346 +10.112, NEUT 6.843+23.557, MONO 0.811 +3.601, EO 0.327 +0.995. For females WBC 7.174+3.037, RBC4.567 +1.086, HB 12.972 +2.752, HCT39.647 +48.186, PLT 264.07+175.079, LYM 2.537+5.005, NEUT 4.769+11.314, MONO 0.460 +0.909, EO 0.188+0.39 Conclusion: The hematological profile of the population in all four provinces of Pakistan differed from the reports of other countries and the standard reference ranges described in the textbook. So, our own hematological parameters must be followed. More studies must be carried out on other age groups and even on adults to strengthen our results.

The PDF was correct.Introduction: Reference hematological values in newborns are informative in evaluation of newborns to determine state of health or disease. For a given population, reference values may differ in accordance with various factors such as age, sex, race, diet, drug intake, altitude, socio-economic status and also the method employed for determination of the values. The aim of this study was to establish reference ranges of complete blood count using umbilical cord blood of normal, healthy, full term neonates born in Manipal Teaching Hospital (MTH), Pokhara, Nepal.Material and Method: The study was conducted in 210 full term, healthy newborns delivered in MTH between Jan 2014 to Feb 2015. Cord blood was collected and a complete blood count was obtained using an automated hematology analyzer.Result: Mean hemoglobin was 15.24 ± 1.96 gm/dl and mean red blood cell count was 4.30 ± 0.63 (range 3.05 – 6.36) X 1012/L. Mean white blood cell count was 14.93 ± 4.44 (range 6.10 ± 31.7) X 109/L and platelet count was 226.88 ± 61.28 (range 105 ± 392) X 109/L. There was no significant difference found in hemoglobin, red cell, white cell and platelet counts between males and females in this study.Conclusion: The values obtained from our study provide ranges for some hematological values in healthy newborns of Pokhara Nepal. However, the hematological reference values for Nepalese cord blood needs to be confirmed by larger numbers of samples from different centers of Nepal.J Nepal Paediatr Soc 2016;36(2):160-164.

Introduction: numerous biological parameters are physiologically modified during normal pregnancy, in particular hematology. The knowledge of these modifications of the maternal body by biologists and clinicians allows the screening of possible anomalies. In Morocco, the reference values of the complete blood count test for pregnant woman are missing, as are those specific to different trimesters of pregnancy. The aim of this study is to look for the reference values for healthy pregnant women of the Northwest region of Morocco, to compare them to those of non-pregnant women (control) and to those of the literature. Methods: blood samples were taken voluntarily from 3898 healthy pregnant women from 18 to 46 years old who presented themselves at the center of health Kalaa and at the service of gynecology obstetrics of the Provincial Hospital Center of M'diq (Morocco), for prenatal care. To establish the reference intervals of the CBC for non-pregnant women, a control group was constituted by 7035 healthy women from 18 to 50 years old selected according to the Moroccan law of blood donation. The CBC was measured on a Sysmex KX21N® analyzer. For each sample a systematic blood smear was done to determine the leukocyte differential. Results: a statistically significant difference between the pregnant women and control group was noted (p < 0.05) for all the hematological parameters: red blood cells, hematocrit, hemoglobin, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, leukocytes, neutrophils, basophils, eosinophils, lymphocytes, monocytes, platelets and mean platelet volume. So, the comparison of the averages established between the first, second and third trimester of pregnancy showed the existence of a significant variation with regard to all the parameters of the CBC test looked for (p < 0.001). Conclusion: the present study provides additional baseline data for basic hematological parameters in healthy pregnant Moroccan women and concluded that pregnancy in women has the tendency to alter some hematological indices. For these reasons, there is an interest to take these modifications into account for optimal maternal and fetal medical care.

Umbilical cord blood (UCB) which is useful in supportive and definitive management of inherited and acquired disorders is usually discarded in our environment. We sought to establish reference values for some haematological parameters of UCB in Makurdi, Nigeria to assist clinicians better interpret results of haematological parameters of UCB. This was a prospective quantitative study that involved analyzing UCB of qualified women to determine its complete blood count, fetal haemoglobin concentration, clotting profile and fibrinogen concentration. Reference ranges of these parameters were thereafter calculated using normal distribution method. The effects of maternal and fetal factors on these parameters were assessed using the Student t-test and ANOVA. The mean total white blood count (TWBC) was 12.3±3.7 x 109/L. Female births had significantly higher TWBC than male births (13.2 ± 3.3 x 109/L vs 11.0 ± 3.8 x 109/L, p=0.003). Babies that weighed 3.0-3.5kg also had significantly higher TWBC (18.9x109L) than those that weighed 2.4-2.9kg (8.7x109/L) p=0.010.Female births had significantly higher haemoglobin concentration (Hb) (13.9g/dl) than male births (11.9g/dl) p=0.001. Similarly, older women aged 32-41 years had significantly higher Hb (13.4g/dl) than those aged 18-24 years (11.6g/dl) p=0.002. Also, women that had more than two children had higher Hb than those who had one or two, (14.7g/dl vs 12.3g/dl) p=0.030. Babies that weighed 3.0-3.5kg at birth also had significantly higher Hb (16.2g/dl) than babies that weighed 2.4-2.9kg (12.3g/dl), p=0.003.The reference values of the haematological parameters of cord blood in our study were similar to what was reported from other developing countries. This study has provided data on haematological parameters of UCB for clinical use in our environment and we recommend routine UCB analysis in order to aid early detection of some inherited and congenital disorder.

Objective This study aims to evaluate the use of umbilical cord blood as an alternative to the admission complete blood count (CBC) in the well-appearing late preterm neonates admitted to the neonatal intensive care unit. Study Design Paired umbilical cord and admission blood CBC samples from well late preterm infants were compared using a two-sample t-test or analysis of variance with an unequal variance for differences in the hemoglobin, platelet counts, white blood cell, and absolute neutrophil counts. Results A total of 100 infants were enrolled in the study. The study included 46 females, 5 Asian, 9 Black, 35 Hispanic, 51 White, with a mean gestational age of 35.3 ± 1 weeks (range: 34–36.5 weeks), and a mean birth weight of 2,347 ± 491 g (range: 1,840–4,260 g). Around 80% were appropriate for gestational age, 5% were large for gestational age, and 15% were small for gestational age. The median difference between the cord and admission blood samples were hemoglobin: 1.1 g/dL, platelet: 7.50 × 103 cells/μL, white blood cell count: 2.3 × 103 cells/μL, and absolute neutrophil count: 0.6 × 103 cells/μL. Conclusion The cord and admission blood testing were not statistically or clinically different when compared. In well late preterm infants, the NICU admission blood CBC may be replaced with an umbilical cord blood CBC.

Background and Objective: Umbilical cord blood which can be obtained by a non-invasive method can be informative about the clinical status of the newborn. It was aimed to establish reference intervals for umbilical cord blood parameters, and to compare complete blood count results between umbilical cord and venous blood samples in this study. Methods: This study was conducted at Medipol University Sefaköy Hospital, Department of Pediatrics, Istanbul, Turkey. A total of 1898 newborns who were born in a two-year period between January 2018 and December 2019 were included in the study. Venous blood samples were taken from 184 of them, and umbilical cord blood samples were taken from 1714 newborns. Results: The percentiles were determined according to gender and delivery method for the hematological parameters of umbilical cord blood. While mean platelet, eosinophil and mean corpuscular volume values ​​were similar between the groups (p>0.05 for each), and significant differences were found between the groups in terms of all other mean hematological parameters ​​(p<0.05 for each). Conclusion: The results of the complete blood count of umbilical cord blood samples can provide reliable information about the newborn. There are significant differences between umbilical cord and venous blood samples in terms of hematological parameters. For these reasons, it is necessary to determine reliable value ranges for umbilical cord blood hematological parameters in newborns. Data of our study can be a guide for further studies and clinicians. doi: https://doi.org/10.12669/pjms.37.2.2526 How to cite this:Gunduz M, Temel H.

Complete blood count (CBC) is the evaluation of blood cells, which provides resourceful information. Considering that inadequate fasting time is the most common pre-analytical error in laboratory diagnosis and is associated with lipemia in blood samples, which has not yet been adequately investigated in dogs, this study aimed to assess diurnal postprandial changes in the CBC of healthy dogs fed with industrialized feed. Eighteen clinically healthy dogs aged 2-6 years and weighing over 6 kg were enrolled in the study. All dogs received “Premium” industrialized feed every 12 hours. Blood was collected after a 12-hour fasting period at 6:00 am (baseline), followed by feeding and new blood samples collected hourly for the next 11 consecutive hours. Red blood cell (RBC) counts, red cell distribution width (RDW), white blood cell (WBC) counts, platelets, mean platelet volume (MPV) and hemoglobin were obtained using an automated veterinary cell counter. Hematocrit (HTC) was determined by Strumia's microcapillary method, differential leukocyte count was performed on hematological dye-stained blood smears and total plasma protein (TPP) was determined using refractometry. Variables were tested for normality and differences were considered significant when p < 0.05. A statistically significant decrease was observed in the erythrogram from 2 h for RBC and hemoglobin, from 3 h for HTC and from 4 h for MCV, persisting until the end of 11 hours. There was no change in MCHC and RDW. Regarding the leukogram, a significant increase in WBC was observed from 2 to 7 h, due to the increase in segmented neutrophils 2 to 8 h following feeding. Lymphocyte counts decreased significantly at 2 and 6 h following feeding. No alteration was observed in eosinophil, basophil, monocyte and platelet counts, as well as in MPV. From 5 h to 11 h after feeding, a significant decrease was seen on TPP. However, changes in hematological parameters did not exceed reference ranges for the canine species. Feeding dogs with industrialized feed caused statistically significant changes in erythrogram, leukogram and plasma protein content. While these changes do not seem to exceed reference values for the species in healthy animals, caution is warranted for sick animals with borderline values, in which these changes might be clinically important depending on the pathologic process.
