University of Surrey researchers demonstrate fingerprint sweat can detect medication levels as accurately as blood tests.

A new study from the University of Surrey aimed at tuberculosis detected antibiotics in the bloodstream using fingerprint sweat with almost the same accuracy as a blood test.

Scientists at the University of Surrey wanted to close this much-needed gap. They conducted a study to evaluate the best time to test for drugs in the bloodstream and determine how much medication a patient has taken.that they decided to work with finger sweat due to their work in forensics. The study “explores what intelligence can be gained by analyzing the chemical composition of a fingerprint left at a crime scene.

They applied this insight to their most recent study into tuberculosis treatment. They gathered a sample pool of ten TB patients at the University Medical Center Groningen in the Netherlands. “We asked patients to wash their hands, put on a nitrile glove to induce sweating, and then press their fingertips onto a paper square.”Scientists detected antibiotics and the metabolite produced by ingesting the drug with 96 percent and 77 percent accuracy, respectively.
