Several microfluidic chips are used to significantly accelerate the time to identify and quantify microbes in a biological sample and test them for antibiotic resistance, particularly for urinary tract infections. A first microfluidic chip uses antibody or similar probes to identify and quantify any microbes present. The same or a similar chip uses antibody or similar probes to identify microbes with DNA or RNA known to indicate antibiotic resistance. Another microfluidic chip tests for antibiotic susceptibility of any microbes by growing them in very small wells in the presence of antibiotics, reducing the time required for such testing by as much as 95%. Another microfluidic chip runs traditional urinalysis or similar tests.
