The HAIR Study

This study aims to develop and evaluate a methodology to test hair samples from returned travellers, who took malaria chemoprophylaxis, in order to determine the concentration of anti-malarial medications in the body. It is important to ensure that adequate protective levels of anti-malarials are being achieved and to look at factors that may influence malaria drug levels attained such as age, sex, adherence or co-medications. Hair samples are often more convenient and easier to manage than blood samples. The testing is absolutely anonymous and we test only for anti-malarials.

For more information and to participate please visit the project page.


We would value your participation if you take anti-malaria chemoprophylaxis and if are willing to donate some hair after travel! For further details, please contact: +41 44 6344630 or patricia.schlagenhauf AT
