Aim: The present study aimed to determine the reference range values for four lipid parameters associated with chronic diseases that were routinely examined in our laboratory in elderly individuals aged ≥65 years.

Materials and Methods: We determined...

Purpose: The maturation of hemostatic system continues from fetal life to adult. Determination of agedependent reference ranges for coagulation is therefore very important to evaluate correctly the hemostasis. The study aimed to establish age-dependent reference range for...

Aim: Reference intervals/ranges are the most widely used decision-making tool in laboratory medicine and serve as the basis for many of the interpretations of test results. There is no agreement on the reference (normal) ranges for serum total 25-hydroxyvitamin D (25(OH)D)...

Aim: In this study, we compared 3 different clot-activator gel tubes to a glass reference tube and evaluated the effect of storage time on 30 different biochemical analytes.

Material and Methods: Blood samples were collected in 4 types of tubes: an...

Aim: Immature granulocytes, an indicator of increased myeloid cell production, are associated with infection or systemic inflammation. Data on the use of immature granulocyte levels as a biochemical marker in infection and inflammatory conditions have been reported. In our...

Aim: Diagnosis and treatment of thyroid disorders are essential for a healthy pregnancy. Physiologic changes that occur during pregnancy affect the functioning of the thyroid gland and thyroid function tests. The aim of this study was to determine the reference ranges of...

Objective: The unnecessary test requesting has significant effect in the laboratory workload. The unnecessary demand and the additional cost of performed tests were discussed through the anemia approach algorithm.

Materials and Methods: We...

Background: The purpose of this study was to investigate the superiority of serum cystatin C levels over serum urea and creatinine in evaluating kidney functions in intensive care unit patients.

Material and Methods: 65 patients in intensive care unit...

Objective: It is reported that the first tests to evaluate thyroid functions in the guidelines of American Thyroid Association (ATA), American Association of Clinic Endocrinologs (AACE) and Turkey Endocrinology and Metabolism Association are thyroid stimulated hormone (TSH)...

Objective: The relationship between thyroid dysfunction and depression remains controversial. Aim of this study was to evaluate the clinical usefulness of the routinely requested thyroid function tests for the psychiatric out patients admitted with the diagnosis of...

Introduction: We aim to emphasize that importance of intralaboratory preanalytical control process with describing two cases of false positive troponin level originated from fibrin gel.Cases Presentation:Troponin test performed on Beckman Coulter Access 2, CA, USA instrument...

Objective: C-reactive protein (CRP) is one of acute phase respondents that has been used to monitor infection and inflammation episodes. In our hospitals' emergency laboratory, CRP analysis is done with a point of care testing device (i-chroma). In our central biochemistry...
