Liver function test at home in Dubai
The liver clears alcohol, medicines and waste, and stores energy. A liver function test shows how well it is coping, often years before any symptom appears.
What the test measures
Complete Liver Function Tests. The standard LFT group, read together, because the pattern across enzymes, bilirubin and proteins says more than any single number.
Total, Direct & Indirect Bilirubin. Bilirubin is a yellow pigment from the normal breakdown of red blood cells; a raised level can reflect a harmless inherited pattern called Gilbert's syndrome, or less often a problem with the liver or bile flow.
AST, ALT, ALP, Gamma GT. Enzymes released when liver or bile duct cells are under strain; ALT is the most liver-specific, GGT often rises with alcohol, and ALP relates to bile flow and bone.
Total Protein, Globulin & A/G Ratio. The liver makes albumin and many other blood proteins, so these numbers reflect how well it is producing them as well as hydration, nutrition and immune activity.
Who should test
Liver problems are usually silent. The most common one today is fatty liver linked with weight, blood sugar and diet, now often called metabolic dysfunction-associated steatotic liver disease. It frequently appears first as a mildly raised ALT on a routine blood test in someone who feels completely well. Picked up early, it often improves with changes to weight, diet, alcohol and activity.
An LFT is also useful if you drink regularly, take long-term medicine, use supplements, or train hard. Strenuous exercise can raise AST for a day or two, and some supplements can affect liver enzymes. Because the screen also measures blood sugar, insulin and lipids, a liver result can be read in context rather than on its own.
- Regular alcohol, including weekend drinking
- Extra weight around the middle, or raised blood sugar
- Long-term medicine or several supplements
- Tiredness, nausea or discomfort under the right ribs
- Yellowing of the skin or eyes, or dark urine (see your own doctor promptly)
- A previous mildly raised liver result that was never rechecked
How to prepare
- Fast overnight with water only, as the full screen includes fasting markers.
- Avoid alcohol for at least 24-48 hours beforehand: GGT and triglycerides respond quickly to a recent drink.
- Skip very hard or new types of training for 48 hours, as muscle strain can raise AST and ALT.
- Keep a list of medicines and supplements to share at your review.
Reading your results
If ALT or AST comes back high
Mildly raised liver enzymes are common and are most often linked with fatty liver, alcohol, some medicines or recent hard exercise. They are usually rechecked after a few weeks of changes. A large rise, or one with other abnormal results, needs prompt follow-up with your own doctor.
If GGT or ALP comes back high
A raised GGT often reflects alcohol or fatty liver, while ALP can rise with bile flow problems or, in younger people, normal bone growth. Reading the two together helps tell these apart. Reference ranges vary by lab, so results are judged against the lab's own range.
If bilirubin comes back high on its own
An isolated, mildly raised indirect bilirubin with normal enzymes is often Gilbert's syndrome, a common and harmless pattern that can rise with fasting or illness. Raised direct bilirubin is less common and warrants further checks.
Reference ranges differ between labs, and a single result is a snapshot. Your consultant reads every value against your history and the rest of the screen, not in isolation.
How the home test works
This test is part of Baseline’s full blood screen: 122 parameters across ten systems from one draw, for AED 850, with results in 48 hours. It is not sold as a single test, because the result means more next to everything else.
- Nurse comes to you. A licensed phlebotomist visits your home or office, 7 days a week, anywhere in the UAE.
- Accredited lab. Samples are processed by a CAP-accredited laboratory (College of American Pathologists), also accredited to ISO 15189, against clinical reference ranges.
- Reviewed with you. Results land in your account in Baseline format, and your consultant walks you through them on video, never a PDF dumped in your inbox.
Ranges are the lab’s own. Your consultant goes through what they mean with you.
Your results arrive in the Baseline app, every marker against the lab’s own range, checked by your consultant before you see them. The values above are an example.
Questions
- Do I need to fast for a liver function test?
- The liver markers themselves are not strongly affected by food, but the full screen includes fasting blood sugar, insulin and lipids. An overnight fast with water only keeps every result reliable.
- Can exercise affect my liver test?
- Yes. Heavy or unfamiliar training, especially weights, can raise AST and sometimes ALT for a few days because these enzymes are also found in muscle. Resting for 48 hours before the draw avoids a misleading result.
- Can a raised ALT go back to normal?
- Often, yes. When ALT is raised because of fatty liver or alcohol, it commonly improves with weight loss, less alcohol, better blood sugar control and more activity. A recheck after about 3 months shows whether changes are working.
- How often should I have an LFT?
- Yearly is reasonable for most adults. Test more often if you drink regularly, take medicine known to affect the liver, carry extra weight or had a previous abnormal result.
