I'd like to perform a small research on a few people for my undergraduate dissertation. I will collect lactate samples from earlobes. Is the consent from the participants enough, or do I need something more?
May be it is like in Scandinavia now that for research belonging to academic studies only informed consent is needed but check with your supervisor who bears the responsibility. And in case you are later going to publish ¨with your supervisor he/she may either already have the permission for this kind of research or applies from the ethical committee for it. Ask.
There are usually some ethical regulations to protect human subjects in research. The consent of the people is one important requirement. You will need to be cleared by your university or another body in your country. This clearance shows that your research complies with ethical standards required when carrying out research with human subjects. Thanks.
