In case of liver injury, transaminases (ALT and/or AST) are released by the liver in the blood stream. LIVER-Screen® rapid test detects these transaminases thanks to specific immunological reagents for each of both transaminases when their concentration is over 80 IU/L. Abnormal transaminases concentrations will be seen through one or two red lines appearance. LIVER-Screen® test should be considered as positive when, in addition to a blue line, one or two red lines, corresponding to each transaminase (ALT and AST), appear. Hepatic problems may indeed lead to an increased concentration of one transaminase only. Evaluation report performed on LIVER-Screen® test shows an overall agreement of 89.2% with the clinical chemistry reference method. Although this test is reliable, false positive or false negative results could be obtained.

Carefully read the instructions before performing the test. The test is only interpretable if the instructions are carefully respected. Follow strictly the indicated time, whole blood and diluent quantities. The kit contains the material necessary to perform a test at home without additional materials. Simply take a blood sample with the easy to use finger lancet, put the sample collected with the pipette into the sample well of the device, by pressing on the pipette bulb. The result should be read within 10 minutes after adding the diluent. LIVER-Screen® test could be performed any time of the day.
