Number connection test

The concentration test was developed to help detect hepatic encephalopathy, a decline in brain function that is caused by increased levels of ammonia in the body.


Connect the numbers from 1 to 25 by clicking on them. You have 40 seconds to complete the test. The timer starts automatically after you have clicked on the first number. 

Remaining time:

The number connection test can not be solved on a mobile device. Please switch to a device with a wider screen to start.
In the meantime you can get a first impression with the liver test above.

Good job!

You have managed to connect all the numbers – your ability to concentrate and your reaction rate are fine. This might indicate that the level of ammonia in your body is normal. However, if you are concerned about any liver-related symptoms, please do not postpone your visit to your doctor.

Time out!

You were not able to connect all the numbers in 40 seconds. The result may indicate both fatigue and increased ammonia levels in the body. Try to do the test again in a few days. If you can’t complete it and/or if you are experiencing symptoms such as distraction or drowsiness, please consult your physician.
