FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine and may be used for detecting biological pathogens in a sample. A clinical indicator unit for detecting biological pathogens comprises a carrier foldable to form two opposite sheets. The inner side of the first sheet of the carrier comprises a contact surface of the sample and an absorbent pad, while on the inner side of the second sheet, there is an indicator surface opposite the contact surface; the indicator surface contains a solvatochromic stain discolouring if a bacterial pathogen is found in the test sample. The unit also comprises a results windows on the outer surface of the second sheet with the absorbent pad engaging a stained reaction zone if the first sheet is folded with the second one. The group of inventions also refers to a version of the above unit wherein the first and opposite second carriers are the two sheets or parts of the same first carrier folded to face each other, and to a method for using the above unit for bacterial infection analysis.

EFFECT: group of inventions enables fast and easy bacteria detection in the sample, and also provides differentiating between bacterial and viral pathogens.
