Abstract
OBJECTIVE
To describe reference values for blood counts obtained from laboratory tests in the Brazilian adult population according to laboratory results from the National Health Survey (Pesquisa Nacional de Saúde - PNS), by gender, age group and skin color.
METHODS
The initial sample consisted of 8,952 adults. To determine the reference values, individuals with prior diseases and outliers were excluded. Mean values, standard deviation and limits were stratified by gender, age group and skin color.
RESULTS
For red blood cells, men presented a mean value of 5.0 million per mm3 (limits: 4.3-5.8) and women, 4.5 million per mm3 (limits: 3.9-5.1). Hemoglobin levels were higher among men with a mean of 14.9 g/dL (13.0-16.9), and in women, 13.2 g/dL (11.5-14.9). The mean number of white blood cells among men was 6.142/mm3 (2.843-9.440) and 6.426/mm3 (2.883-9.969) for women. Other parameters showed close values between the genders. Regarding age groups and skin color, mean values, standard deviation and limits of the exams presented small variations.
CONCLUSION
Hematological reference values based on the national survey allow for the establishment of specific reference limits for gender, age and skin color. The results presented here may contribute to the establishment of better evidence and criteria for the care, diagnosis and treatment of diseases.
目的根据巴西国家健康调查(Pesquisa Nacional de Saúde - PNS)的实验室结果,按性别、年龄组和肤色描述巴西成年人实验室验血计数的参考值。方法初始样本为8952名成人。为了确定参考值,排除了有既往疾病和异常值的个体。平均值、标准差和极限按性别、年龄组和肤色分层。结果对于红细胞,男性的平均值为500万/ mm3(限制范围:4.3-5.8),女性为450万/ mm3(限制范围:3.9-5.1)。男性的血红蛋白水平较高,平均为14.9 g/dL(13.0-16.9),女性为13.2 g/dL(11.5-14.9)。男性的平均白细胞数为6.142/mm3(2.843-9.440),女性为6.426/mm3(2.883-9.969)。其他参数在性别之间显示出接近的值。在年龄组和肤色方面,检查的平均值、标准差和限变化较小。结论基于全国调查的血液学参考值可建立性别、年龄和肤色的具体参考值。本文提出的结果可能有助于为疾病的护理、诊断和治疗建立更好的证据和标准。
期刊介绍:
Revista Brasileira de Epidemiologia (Brazilian Journal of Epidemiology) - every four months, journal published by the ABRASCO - aims at publishing not previously published Original Articles, including critical reviews on specific themes, which may contribute to the development of Epidemiology and related Sciences. Revista also publishes articles in the following categories: Debate aimed at discussing different views of the same theme which may be presented as an original article followed by comments from other authors, reproduction of panels and other similar formats; Notes and Information - notes on primary results of research studies.
