Body fluid testing device having improved illumination

A body fluid testing device having illumination, the testing device comprising:

• a test unit including:
• a sample part having a sheet portion, with body fluid of a user configured to be applied onto a first surface thereof;
• a casing hole;
• a sheet mounting portion coupled to the casing hole and formed with an insertion hole for allowing the sample part to be inserted therethrough;
• an illumination part having an insertion module formed with an insertion port to receive the sample part and a light source for providing light to the sample part, wherein the sample part comprises an electrode portion provided with a conductive pattern;
• a battery for supplying power to the illumination part;
• a casing receiving a lens group for magnifying the body fluid applied onto the sheet portion;
• and
• a reflector provided in an inner side of an upper casing to reflect the light emitted from the light source to the sheet portion;
• and
• a user terminal comprising a camera to take an image of the sample part magnified by the lens group, prior to analyzing the image by the user terminal,
• wherein the conductive pattern of the electrode portion is configured to form a closed circuit when the sample part is inserted into the test unit, wherein the closed circuit supplies power of the battery to the light source to cause the light source to automatically emit the light to the sheet portion when the sample part is inserted into the test unit.
