The Reitan Test (number connection test) is a commonly used bedside test that is useful for screening for hepatic encephalopathy. Part B of the test may follow completion of part A, but is not used by all clinicians.
- 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 and letters on the sample for part B (lower box), alternating between the numbers and letters (ie, 1-A-2-B-3-C, etc).
- Step 3: Inform the patient that you will be timing the test and to complete the number-letter connections from 1 to L 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. An average score is 75 seconds, while >273 seconds is considered deficient.
