Ethical Approval


When reporting trials on human subjects, authors should indicate whether the procedures were in accordance with the ethical standards set by the responsible human experimentation committee (institutional and national) and latest version of the Declaration of Helsinki given by World Medical Association. Ethical approval (institutional or national) should be obtained for every study that includes a collection of additional patient sample of any biological material (more than those required for the medical evaluation).

All subjects should sign an informed consent form and this information should be provided in the manuscript. Signed informed consent forms should be archived by the authors. The authors have to provide a statement that they have received and archived all patient informed consent forms, as required during the manuscript submission process. It should be noted that informed consent to participate in the research does not imply consent to publish personal individual data (names, pictures, hospital identification). Therefore, for publication that includes any individual data, patient must give his written consent. This is especially applied when it is not possible to obtain anonymity of the data without distorting scientific evidence.

Regardless of the preserved anonymity, patients presented in case report articles should always sign informed consent. Case reports without patients’ consent are not eligible for publication in Jurnal Teknologi Laboratorium (Journal of Laboratory Technology)Specific types of case reports, extra-analytical mysteries, are not obliged to obtain informed consent as long as there are no patient’s personal data revealed. If there is need to publish patient’s rare diagnosis or specific demographic or personal data by which patient’s identity can be implied, than the authors must obtain patient’s signed informed consent.

In the spirit of promoting best practice guidelines given by COPE (available at:, Jurnal Teknologi Laboratorium (Journal of Laboratory Technology) will not consider for publication manuscripts in which best ethical practice is not ensured, i.e. Informed consent is missing and/or Ethical approval is omitted. To simplify the decision-making process on whether a type of study requires Informed consent and/or Ethical approval, authors are encouraged to consult the table below reprinted from Borovecki A, Mlinaric A, Horvat M, Supak Smolcic V.
