Objective: IUrinary tract infection (UTI) is a common disease in children. Rapid and reliable diagnosis of UTI is mandatory for the prevention of complications. The aim of the present study was to assess whether or not automated urine analysis can be used as a rapid diagnostic...

Objective: Thyroid function tests (TFT) are the most frequently requested endocrine tests from clinical laboratories. Although the guidelines published by the American and British Thyroid Associations suggest the use of thyroid stimulating hormone (TSH) as a first step test...

Aim: Vitamin D deficiency is a common public health problem in our country. It is possible to find data reaching 90% in studies about determining deficiency prevalence. In recent years, this deficiency has been attracted the attention of the press and has directed people to...

Objective: Use of C-Reactive protein in the follow-up of different clinical situations is getting more important. Levels of CRP can be detected by immunonephelometric and immunoturbidimetric methods in the clinical laboratories. The emergency departmentÕs laboratory renders...

Aim: Laboratory results have an important effect on the clinical decision-making process. For this reason, the analysis and reporting quality of the tests is extremely important. Measurement uncertainty is the quantitative expression of the quality of test results. It is...

Objective: High Performance Liquid Chromatography (HPLC) is widely used to classify hemoglobin fractions in screening of hemoglobinopathies. We, here in this study, detected the “measurement uncertainty” of the pivotal parameter in thalassemia screening, namely HbA2; and...

Objectives: There are not enough studies based on laboratory results regarding the prevalence of Substance Use Disorders in our country, The purpose of this retrospective study is; to determine the distribution of the substances used by dependent individuals with treatment...

Aim: In this study, we aimed to evaluate the preanalytical process performance by six sigma method and make the necessary arrangements according to the obtained results in our laboratory.

Background: The aim of this study is to assess the results of inspections in the last three years on drug abuse testing in medical laboratories according to the last regulations in Turkey.

Materials and Methods: The on-site inspections of medical...

Aim: Since glomerular filtration rate (GFR) determined by 24 hours urine is cumbersome, nephrologists recommend using an estimated GFR (eGFR). This study aimed to investigate the agreement between Modification of Diet in Renal Disease (MDRD) and Chronic Kidney Disease...

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...

Objective: Troponin I is a reliable and sensitive marker which is used to evaluate the myocardial injury. However there are different cut-off values for Troponin I due to different measurement technics. Therefore it is recommended that laboratories must define their own...

Aim: It was aimed to determine predictive markers for the need for intensive care unit (ICU) hospitalization in patients with coronavirus infection.

Material and Methods: This study was performed retrospectively from data of patients hospitalized with...

Objective: Anemia is a commonly encountered health problem. In this study, togetherness of beta thalassemia trait with iron deficiency anemia was investigated using by some biochemical and hematological cell count indices.

Material and Methods: The...

Objective: Test analyses in laboratories must leave neither clinician nor patient in doubt. Measurement uncertainty must therefore be studied for all tests in laboratories. The aim of this study was to calculate the measurement uncertainty of the hormone...

Aim: Measurement uncertainty provides information about the limits at which the measured value may vary as a result of random effects in a biochemical measurement. It is a quantitative indicator of the quality of the result obtained and allows us to estimate the extent to...

Aim: Hereditary thrombophilia is a condition where there is an increased tendency for clot formation due to a genetic variation in the coagulation system. Genetic testing in cases with a preliminary diagnosis of thrombophilia is necessary to confirm the diagnosis, eliminate...

Objective: The aim of this study is to investigate the compatibility of bicarbonate (HCO3-) levels measured by blood gas meter in serum autoanalyser.

Materials and Methods: In the study, serum bicarbonate and blood gas bicarbonate levels of 186...

Objective: To compare the analytical performance of 2 immunoturbidimetric C-reactive protein (CRP) reagents using the same automated analyzer and to evaluate whether an alternative reagent provides clinically acceptable results.
