Objective: In this study we aimed to calculate the reference intervals of carbohydrate antigen 15-3 (CA15-3), carbohydrate antigen 19-9 (CA19-9), carbohydrate antigen 125 (CA125) and carsinoembriyogenic antigen (CEA).

Materials and Methods: 325 healthy...

Objectives: The carbohydrate antigen 19-9 assay is a widely used biomarker as a complement to other tests in the detection and follow-up of pancreatic, bile duct and colon cancer in high-risk individuals. The CA 19-9 assays often give different results with different...

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...

Search for other markers increase in prostate cancer diagnosis due to the lack of prostate-specific antigen, but it has not yet found more sensitive and specific method to make diagnosis by exposing patients less treatment. The exact diagnosis of prostate cancer continues to be made by...

Ovarian cancer has often been described as a “silent killer,” but recent studies have shown that there are symptoms that appear in the early stages of the disease. Recognition of these symptoms is critical because early diagnosis improves the probability of cure. Use of serum biomarkers for the...

Aim: Regarding coronavirus disease (COVID-19), despite antibody measurement alone providing insufficient data, studies evaluating immune responses to vaccination or disease have focused on humoral immunity. Uncoupled humoral and cellular responses may be present after...

D-dimer antigen is a fibrin degradation product that is formed by the sequential action of three different enzymes on cross-linked fibrin. As such, increased levels of plasma D-dimer should be reliable indicator of thrombus formation. The D-dimer antigen is a specific marker of fibrin clot...

Aim: Pancreatic cancer (PC) is a disease with complex and poorly understood etiology. One of the common risk factors of PC is diabetes mellitus (DM). Increased carbohydrate antigen (CA) 19-9 levels can be used as a biomarker in diagnosis of PC. However, CA 19-9 levels have...

Objective: The aim of study was to determine unnecessary repeated total prostate specific antigen(tPSA) according to minimum retest interval and to evaluate the change between consecutive measurement results with RCV.

Material and Methods: According...

Objective: Prostate specific antigen (PSA) and ma ny other tumor markers are suggested to be useful for the biologic activity of the prostate cancer. The aim of our study is to investigate possible relationship between inflammatory markers (high sensitive C-Reactive Protein...
