The Reitan Test (number connection test) is a commonly used bedside test that is useful for screening for hepatic encephalopathy.
- Step 1: Make sure that the patient is alert enough to cooperate for this test, can see adequately, has a writing surface, is able to count, and can hold a pen or pencil.
- Step 2: Demonstrate to the patient how to connect the numbers on the sample for part A (lower box).
- Step 3: Inform the patient that you will be timing the test and to complete the number connections from 1 to 25 as fast as the patient can without lifting the pen or pencil from the paper.
- Step 4: If an error occurs, point it out immediately and allow the patient to correct the error. The total elapsed time to complete the test, including the time spent correcting errors, is the score.
- Step 5: Record the time spent to complete the test. If it takes longer than 3 minutes to complete test A, record ">3 minutes" as the score.
An alert person without hepatic encephalopathy should be able to complete part A of the test in seconds similar to their age in years.
