Albumin is a protein that is made in the liver and is a good indicator of liver or kidney disease. Albumin is a transport protein for several substances including calcium, zinc, free fatty acids and bilirubin.  It also has important functional roles such as the transportation of hormones and drugs. It also helps to maintain the oncotic pressure within blood plasma and so prevents fluid from leaking out of the bloodstream. Albumin is the most abundant protein found in the blood.

Why Take An Albumin Blood Test?

The purpose of an albumin blood test is to check for certain health conditions such as liver problems. It is usually tested along with other biomarkers associated with live health such as alanine aminotransferase (ALT), alkaline phosphatase (ALP), bilirubin, gamma GT, globulin and total protein.  If the amount of circulating albumin is low, then this can be an indication of liver or renal damage.

What Role Does Albumin Play In The Body?

The concentration of circulating albumin in the blood is directly associated with liver health as well as nutritional status.

Low albumin levels (known as hypoalbuminemia) can also be a sign of malnutrition. The process of eating stimulates the production of albumin in the liver and keeps the amount of albumin in the blood at a regular level. However, malnutrition or individuals consuming a low protein diet may present with low levels.

Albumin levels can also affect calcium and other protein-bound biomarker levels. In the blood, calcium is bound to proteins, mainly albumin. Therefore, if the albumin concentration is low then this can also reduce the total calcium concentration too.

How Does Albumin Affect Your Wellbeing?

A high albumin level is 51.5< g/L.  Higher than normal albumin levels can be caused by dehydration. The most common causes of dehydration are a poor fluid intake and can occur due of vomiting, diarrhoea, burns, fever or urinary issues. Certain drugs such as steroids can raise albumin levels, and so to can hormones such as insulin. That’s why is a good practice to check your liver health over time to establish your own personal albumin levels. 

A low albumin level is <33.95 g/L and could be a sign of malnutrition, liver disease or an inflammatory disease.

The liver can become diseased through infection e.g. hepatitis, increased/excess alcohol consumption, poor diet e.g. non-alcoholic fatty liver, trauma, inherited factors such as haemochromatosis and immune system issues e.g. primary biliary cirrhosis.

When the liver is damaged it reduces its production of albumin and so there is a decreased concentration within the blood. Research has shown that advanced liver disease results in severe oxidative damage to albumin and has a reduced binding with bilirubin, a substance produced when red blood cells break down. The bilirubin binds to albumin where it is transported to the liver for excretion.

Normal albumin levels are between 35 – 50 g/L, Forth customers have an average albumin level of 41.46 g/L.


How To Improve Albumin Levels With Diet

Diet is a major factor in the health of the liver. The liver has important functions in the human body including the detoxification of chemicals, metabolism of drugs and blood filtration. Individuals with non-alcoholic fatty liver disease tend to eat highly calorific diets which mainly consist of carbohydrates and fats. Therefore, it is essential to eat a healthy, balanced diet to ensure the liver remains healthy.  Make sure you are eating a good amount of dietary fibre as this will help to keep your digestive tract healthy, the liver filters the blood from the digestive tract. Good sources of fibre are fruit, vegetables and wholegrains. Eating lots of simple carbohydrates like white bread, cakes and pastries can increase blood glucose levels rapidly and lead to weight gain, so you need to be aware of how much you are eating. Swapping simple carbohydrates for wholegrains will slow down the rise in blood sugar, are healthier for the liver and are high in fibre.

Improving Albumin Levels Through Hydration

Hydration is another important factor, particularly if your albumin levels are increased. The liver is approximately 73% water and needs water to function. A lack of water can also mean the liver has to compensate by helping the kidneys and so can accumulate more fat. Try to drink around 2 litres of water per day, although this may need to be increased if you are exposed to hot temperatures or are exercising. Alcohol doesn’t contribute to our hydration status, in fact, it causes dehydration because it causes increased urination. Alcohol also harms the liver and can be a major contributory factor for liver disease.

Common Symptoms Of Liver Disease

The most common symptoms of liver damage are feeling tired and weak all or most of the time, reduced appetite, loss of libido, jaundice (yellowing of the skin and whites of the eyes), itchy skin and nausea and/or vomiting.
