Whether positive or negative, a self-test result is a starting point for a conversation about your symptoms with your doctor. Self-testing provides a preliminary screen of physiological biomarker levels, but is not a diagnosis. Always speak with your doctor if you are concerned about your symptoms or anxious about your health.

Intended use
The SELFCHECK Liver Health Test is registered with MHRA as a CE certified, in-vitro diagnostic medical device for self-testing.
- Finger-prick blood test
- Safe and easy to use
- Results at home in minutes
- CE certified for self-test use
Contains 1 test.
The test is a manual, qualitative, immunochromatographic (lateral flow), screening self-test for the immunological detection of two liver enzymes, alanine transaminase (ALT) and aspartate transaminase (AST) in a finger prick whole blood sample. The test is for use at home by members of the public for checking the physiological status of the liver.
General information
Liver disease is almost entirely preventable, with the main risk factors being alcohol consumption, obesity, and hepatitis. The liver is the body's second-largest organ and plays a vital role in maintaining good health, by:
- Removing toxins, such as drugs and alcohol from the body
- Producing bile which helps with the digestion of fats
- Helping to fight infections
- Controlling cholesterol levels
Liver disease typically does not cause noticeable symptoms until it has progressed significantly and the liver has sustained damage. At this stage, symptoms may include loss of appetite, weight loss, and jaundice. Speak with your doctor if you have any symptoms of liver disease, or are concerned about your health.
Some of the most common blood tests for liver function include the transaminase enzymes aspartate transaminase (AST) and alanine transaminase (ALT), which are released by the liver when it is damaged. Although ALT is found mainly in the liver, AST is less specific, as it can also be present in heart muscle and other tissues.
Time to result
The test gives a result in 10 minutes at home.
Warnings
A screening test for biomarkers, such as ALT or AST is not a diagnosis. A negative result cannot rule-out liver disease.
Not following the instructions exactly as written in the instructions for use may cause a false positive or false negative result.
Do not change your medication, diet or lifestyle solely on the basis of a self-test - always discuss your result with an appropriate healthcare professional first.
Accuracy
This test has a cut-off of 80 IU/L of ALT/AST for a positive result and is calibrated to the International Federation of Clinical Chemistry (IFCC) international reference method.
The test has an overall agreement of 95.83% (89.19 to 99.04)*, sensitivity of 98.36%, and specificity of 91.43% with laboratory tests for ALT/AST. Although this test is reliable for the detection of these liver enzymes, all medical tests can give false positive or false negative results.
IMPORTANT: These figures refer to the agreement of the SELFCHECK test with laboratory ALT/AST tests, and not to the accuracy of tests for the diagnosis of liver disease.
