OBJECTIVES To define and discuss reference ranges for commonly determined laboratory parameters in healthy adults from southern Tanzania. METHODS A population-based sample of adult volunteers from Mbeya, Tanzania, who were not HIV positive or showing signs and symptoms of other diseases, participated in this study. We enrolled 145 women and 156 men between 19 and 48 years of age to determine ...
Background: Prostate cancer is the third most common malignancy in men worldwide. Despite being a helpful biomarker in prostate cancer, prostate specific antigen (PSA) is affected by different factors including age, lifestyle, geographical region and ethnicity. Objective: To determine the age specific serum PSA level among healthy Northern Iranian men and to compare the results of our study wit...
OBJECTIVE To determine the reference ranges of lymphocyte subsets in serologically HIV-seronegative healthy male adults in Oman. METHODS A cohort, of 118 healthy male blood donors ranging in age from 18-51 years, was included in the study. The average age was 25 years. Blood samples collected into tubes containing ethylene-diamine-tetra acetic acid were investigated for lymphocyte subsets usi...
OBJECTIVES When laboratory Reference Ranges (RR) do not reflect analytical methodology, result interpretation can cause misclassification of patients and inappropriate management. This can be mitigated by determining and implementing method-specific RRs, which was the main objective of this study. DESIGN AND METHODS Serum was obtained from healthy volunteers (Male + Female, n > 120) attending...
Objectives This study was done to evaluate the normal fetal cerebral lateral ventricle dimensions with transabdominal ultrasonography. The atrial width (AW), ventricle-to-choroid measurement (V-C), ventricle-to-hemisphere ratio (VHR), and combined anterior horn measurement (CAHM) were taken. Methods This was a cross-sectional study involving 400 normal singleton pregnant subjects whose gestatio...
DOI: 10.5581/1516-8484.20110106 The development of this work focused on the establishment of new reference values for the complete blood count (CBC) in the city of Curitiba as this was last studied back in the 1980s.(1,2) With the improvement in cell counting and analysis technologies, the need to update hematologic reference values is evident with the inclusion of the new parameters provided b...
A normal range for IgG1, IgG2, and IgG3 subclasses has been established for children aged 6 months to 5 years using commercially available monoclonal antisera. Of particular interest were the very low concentrations of IgG2 in some healthy children, a finding which casts doubt on the importance of IgG2 deficiency reported in some patients with otherwise unexplained infections. It was not possib...
We measured Na, K, Cl, glucose, hemoglobin, erythrocytes, and hematocrit in the serum or blood from approximately 800 male and 200 female second-year medical students in an effort to define the size of an acceptable reference population. Using the data from the men and Monte Carlo simulations of 10-400 samples, each carried out 5000 times, we found that for most of the above tests, approximatel...
Introduction Measurement of immuno-hematological parameters has been historically helpful in the diagnosis and treatment monitoring of many infectious diseases and cancers. However, these parameters have not yet been established in many developing countries where patient care strongly relies on such low-cost tests. This study describes the immuno-hematological parameter ranges for Malian health...
Measuring interrupter resistance (R(int)) is an increasingly popular lung function technique and especially suitable for preschool children because it is simple, quick and requires only passive cooperation. A European Respiratory Society (ERS)/American Thoracic Society (ATS) Task Force recently published empirical recommendations related to procedures, limitations and interpretation of the tech...
