Introduction: Reference intervals (RIs) of blood parameters vary between gender and age. Therefore, it is important to establish specific RIs for the population served. To interpret the reports of elderly population, laboratories use RIs of adults (>18 years old). In calculation of RIs, healthy population is used in direct method while patient data...

A comparative cross-sectional study was carried out on people living in the vicinity of a tyre factory and on age and gender matched people in about 8km away from the factory. Details of the respiratory symptoms were obtained by an investigator administered questionnaire. Respiratory system was examined by medically qualified investigators. FVC, FE...

Conventional method of calculation of reference interval (RI) for complete blood count (CBC) parameters for elderly population is challenging as finding healthy elderly volunteers is difficult. This study was carried out to assess the possibility of use of stored patient data of CBC reports of elderly patients in calculation of RI for CBC parameter...

Introduction: Conventionally, to examine stained blood smears, bright field microscope (BFM) is used. Appreciation of outlines and three-dimensional images of cells is possible with optical phase contrast microscope (OPCM) in wet smears Methods: This study was performed to determine applicability of OPCM in reporting anisopoikilocytosis in stained...

Article is about haematological characteristics of patients with chronic kidney disease

This study was carried out to determine gaps in knowledge, practices and attitudes on laboratory safety among technical personnel. Data were collected using open and closed ended questionnaire.

Exposure to asbestos causes health hazards including asbestosis, mesothelioma and lung cancer. Asbestos industry workers are at a higher risk of exposure. Objective of this research is to assess the health status and the safety practices of asbestos industry workers. Four hundred seventy-five workers from three asbestos sheet manufacturing factorie...

Introduction: Erythropoietic response following chemotherapy and stem cell transplant is assessed by reticulocytosis and immature reticulocyte fraction (IRF). They are not used to assess erythropoiesis following acute haemorrhage even though it is known to cause reticulocytosis. This study was performed to evaluate the use of IRF as a marker of...

Health Status and Safety Practices of Workers of Asbestos Sheet Manufacturing Factories in Sri Lanka.

Calculation of reference intervals (RI) for each quantitative test for the population served is mandatory in clinical care. Standard method of calculation of RI is costly and tedious. Literature show success in using patient data in calculating RI for some tests but, those related to complete blood count (CBC) are sparse. Therefore, this study was...

Objective: Red cell indices and parameters are used to screen beta-thalassemia trait (BTT). Different red cell indices and formulae used to discriminate BTT in different populations show inconsistent results. Methods: A retrospective study was performed to assess reliability of 11 red cell indices, parameters and formulae in differentiating BTT...

LUNG FUNCTIONS OF WORKERS OF ASBESTOS RELATED INDUSTRY IN SRI LANKA: A CASE-CONTROL STUDY

LUNG FUNCTIONS OF WORKERS OF ASBESTOS RELATED INDUSTRY IN SRI LANKA: A CASE-CONTROL STUDY

Purpose: In diabetes, generalised microvascular disease and coronary artery disease (CAD) are likely to occur in parallel. We used a sidestream dark field (SDF) handheld imaging device to determine the relation between the labial microcirculation parameters and CAD in asymptomatic patients with diabetes. Methods: SDF imaging was validated for as...

The development of renal ischemia has been postulated to be a main cause of the progressive nature of kidney diseases. In recent years, it has become clear that inappropriate and sustained activation of the endothelium could mediate this phenomenon. Endothelial activation will result in leucostasis and can compromise peritubular flow. The associate...
