Albumin blood test: normal range, low albumin and price in the UAE

An albumin blood test measures the main protein in the liquid part of your blood. Albumin is made by the liver, so the result says something about the liver, but it also moves with inflammation, with losses through the kidneys or gut, with hydration and with pregnancy. Low albumin is the result people ask about most, and it is a pattern to explain rather than a diagnosis.

What albumin is and what it does

Albumin makes up 55 to 60% of the protein in serum, the fluid left when blood clots. It is made in the liver and nowhere else, at about 10.5 grams a day in a 70 kg adult. The body's albumin turns over roughly every 25 days, and its half-life is about 17 days.

It has two main jobs. It holds water inside the blood vessels, and it carries other substances through the blood, including fatty acids, bilirubin, thyroid hormone and many medicines. About half of the calcium in blood is also carried on proteins, mainly albumin.

Normal range

Albumin is reported in grams per litre (g/L) or grams per decilitre (g/dL), depending on the laboratory; 1 g/dL equals 10 g/L. Published adult ranges differ from one source to the next:

Source	g/L	g/dL
MedlinePlus (US National Library of Medicine)	34 to 54	3.4 to 5.4
An NHS hospital laboratory in England	35 to 50	3.5 to 5.0
University of Washington laboratory medicine	39 to 52	3.9 to 5.2

The spread is real. An analysis of more than a million albumin results from primary care in England found differences between laboratories large enough to matter clinically. It also found that albumin peaks around age 20 and then drifts down with age, falling faster in women until men and women converge around 60. Ranges vary by laboratory, method, age and sex, so the range printed on your own report is the one to read your result against.

What a low albumin usually points to

Inflammation is one of the most frequent reasons. During an infection, after an operation or injury, or in a long-running inflammatory condition, small blood vessels let more albumin leak into the tissues and albumin is broken down faster, so the level in the blood falls even while the liver keeps making it. After an operation, albumin can keep falling for 3 to 7 days and may take 3 to 4 months to return to normal.

Other patterns a doctor considers:

• Liver. A liver with advanced scarring makes less albumin, so a low result next to abnormal liver enzymes, bilirubin or clotting tests carries more weight. On its own, albumin is a blunt measure of liver function, and the British Society of Gastroenterology warns against over-reading it.
• Kidneys. Some kidney conditions let albumin leak into the urine. A urine albumin-to-creatinine ratio shows whether that is happening.
• Gut. Conditions that limit absorption, such as coeliac disease or Crohn's disease, or that let protein leak from the gut.
• Nutrition. A very low protein intake can lower albumin, but less than people tend to assume. Undernutrition without inflammation lowers it little, if at all.
• Pregnancy. A lower albumin is normal in pregnancy.

What a doctor usually looks at next: the rest of the liver function test, a marker of inflammation such as CRP, a urine test for protein, and your symptoms and history. A low result during or just after an illness is read differently from a steady fall across several tests taken while you were well.

What a high albumin usually points to

A truly high albumin is uncommon. The usual reason is dehydration, which concentrates everything in the blood. A tourniquet left on for a long time during the draw can push the result up artificially. Some medicines, including anabolic steroids, androgens, growth hormone and insulin, can also raise it. A mildly high value is often simply repeated before anything is read into it.

What moves the result

• Posture. Standing moves water out of the blood vessels. In a study that sampled the same people lying, sitting and standing, albumin and total protein rose by a meaningful amount between sitting and standing, which is why the position for the draw should stay the same from test to test.
• Hydration. Dehydration nudges albumin up. Drinking very large amounts of water, or receiving a large volume of intravenous fluid, can dilute it.
• A recent illness. An infection, injury or operation can lower albumin for weeks.
• Not eating. Going without food for 24 to 48 hours can lower it.
• Pregnancy and medicines. Pregnancy and some medicines, including birth control pills, can lower it.
• Method. The common dye-based methods can read falsely high when albumin is low, which is one reason laboratories differ.

Preparing for the test

Albumin on its own needs no special preparation. It is usually taken with other tests, though, and a liver function test often comes with an instruction to fast for 10 to 12 hours, so follow the instruction for the whole draw. Tell the person taking the sample about any medicines you take; whether anything changes before a test is a question for your doctor.

How Clare's panel handles it

In Clare's panel, albumin is measured by the lab. Clare then uses it in two calculated results: globulin, which is total protein minus albumin, and the albumin/globulin ratio, which is albumin divided by globulin. Albumin sits in the liver group of the panel, beside the liver enzymes, bilirubin and total protein.

Price

Albumin is usually sold within a liver function test rather than on its own. When we read public prices on 11 October 2026, a liver function test cost from 89 to 1,100 at six UAE providers; the top of that range was a hospital package that adds other tests. VAT is rarely stated, some are offer or "from" prices, and home collection can add a fee.

Related tests

Albumin is read most usefully with total protein, which shows what the rest of the blood's protein is doing; with CRP, which shows whether inflammation could explain a low result; and with calcium, since a low albumin can pull total calcium down with it. Albumin is also one of the inputs to PhenoAge, a biological age score explained in Biological age: what the number is, and what it is not.

Why it means more over time

In health, albumin is a slow, steady marker, so a change between tests says more than a single number near a range limit. A drop across two tests taken while you were well is worth discussing with a doctor, with both results in front of you. A dip during an illness that recovers over the following weeks or months is the expected pattern. How often albumin is rechecked depends on why it was measured: a doctor following a liver, kidney or gut condition sets the interval, and in a yearly panel it is read against last year's value.
