Turkish Journal of Clinics and Laboratory

Information on the standard requirements for manuscripts submitted to medical journals can be found on the website www.icmje.org

Aim and Scope:

The Turkish Journal of Clinics and Laboratory is a peer-reviewed, open-access, and periodically published journal owned by DNT Middle East Publishing Inc. Our aim is to publish high-quality scientific articles that include innovations in the diagnosis and treatment of diseases on an international platform. It is a scientific medical journal published four times a year.

As a peer-reviewed journal, submitted manuscripts are initially evaluated by consultants in terms of compliance with the common standards defined by the International Committee of Medical Journal Editors (ICMJE) for biomedical manuscripts (available at www.icmje.org).

The journal publishes retrospective/prospective clinical and laboratory studies, interesting case reports, invited reviews, letters to the editor, original images, short reports, and surgical technique articles in all fields of medicine. Manuscripts that have been published elsewhere or are under review in another journal, or that are not prepared according to the journal’s guidelines, will not be accepted for evaluation.

Online Manuscript Submission:

All correspondence and manuscript submissions must be made via DergiPark at https://dergipark.org.tr/tjcl. Detailed submission information can be obtained from this website. A unique number will be assigned to each submitted manuscript, and confirmation of receipt will be sent via email. Full-text PDF versions of published articles are available on this page.

Open Access Policy:

The Turkish Journal of Clinics and Laboratory is an open-access journal. Users can access full-text articles freely and use them in scientific studies with proper citation.
