Urea is waste product produced as the body digests protein and is carried by the blood to the kidneys, which filter the urea out of the blood and into the urine. The urea test examines how well the kidneys are functioning.
Raised levels of urea in the blood can be caused by dehydration or high protein consumption or may indicate that the kidneys are not working properly.
Low amounts of urea in the blood may indicate a low protein diet, excess hydration, malnutrition or liver failure.
Creatinine is a chemical waste molecule that is generated from muscle metabolism. Measurement of this is an indicator of the levels of other waste products in the body. Creatinine is an accurate marker of kidney function.
Elevated creatinine can be caused by high intake of animal protein, taking creatine supplements and vigorous exercise but can also indicate that the kidneys are not working properly.
Low creatinine can be caused by a low protein diet, reduced muscle mass or sometime that the kidneys are simply functioning efficiently.
The estimated glomerular filtration rate (eGFR) assesses how well the kidneys are working by estimating the amount of blood filtered through the kidneys. The glomeruli are tiny filters in the kidneys responsible for removing waste products. If these filters do not do their job properly, kidney function can be impaired. The eGFR calculation is an estimate of actual glomerular filtration rate, calculated using your age, gender and serum creatinine levels.
A normal or high eGFR indicates good kidney function.
A low eGFR result can indicate your kidneys are not working as well as they should. eGFR can be used to assess the severity of chronic kidney disease (CKD).
It is important to note that individuals with high muscle mass as well as people of certain ethnicities can have a low eGFR which is normal for them. If kidney damage is suspected then other investigative tests are recommended.
Bilirubin is a product of haemoglobin breakdown. It is removed from the body via the liver, stored and concentrated in the gall bladder and excreted into the bowel. Elevated levels can cause the skin and whites of eyes to become yellow (jaundice) as the liver is unable to remove enough bilirubin from the blood. This can indicate liver damage.
Bilirubin can also be raised due to a blocked bile duct as well as Gilbert's Syndrome.
Alkaline phosphatase (ALP) is an enzyme found mainly in the liver and bones. Raised levels can indicate bone or liver disease. Elevated ALP is assessed in conjunction with other liver function tests to determine whether the problem lies in the liver or the bones.
Pregnancy can also cause raised ALP and it is often elevated in growing teenagers.
Alanine transferase (ALT) is an enzyme which is produced by the liver and can indicate liver damage caused by alcohol, drugs or viruses (hepatitis). Small amounts of ALT are normal, but raised levels may indicate that your liver is inflamed.
Elevated levels of ALT can also be caused by recent vigorous exercise.
CK (creatine kinase) is a muscle enzyme which signifies muscle cell damage and death. CK levels tend to be higher in people with greater muscle mass.
The level of CK in the blood is measured to assess muscle damage - it can rise rapidly after muscle trauma, but will subside as the damage repairs. If CK continues to rise it indicates that muscle damage is not being repaired. If you have been to the gym the day before your blood test you may well exhibit raised levels of CK.
Gamma GT is a liver enzyme which is raised in liver and bile duct diseases. It is used in conjunction with ALP to distinguish between bone or liver disease. Gamma GT is also used to diagnose alcohol abuse as it is raised in 75% of long term drinkers.
Total Protein represents the sum of albumin and globulin. Abnormal levels can indicate malnutrition as well as a liver or kidney disorder.
Albumin is made mainly in the liver and helps to keep the blood from leaking out of blood vessels. It also helps carry some medicines and other substances through the blood and is important for tissue growth and healing.
Low albumin levels can indicate liver disease and can also be a marker for chronic ill-health, malnutrition and inflammation. It can also occur in kidney conditions such as nephrotic syndrome and diabetes.
Raised levels are usually caused by dehydration.
Globulin consists of different proteins and is made by the liver and the immune system. Certain globulins bind with haemoglobin while others transport metals, such as iron, in the blood and help fight infection.
Uric acid is a waste product from the digestion of protein. High levels may lead to excess uric acid being deposited as crystals in the tissues of the body. When this occurs in joints it causes the painful condition known as gout.
HbA1c or Haemoglobin A1c is also known as glycosylated haemoglobin and is a longer term measure of glucose levels in your blood than a simple blood glucose test. Glucose attaches itself to the haemoglobin in your red blood cells, and as your cells live for around 8-12 weeks it provides a good indication of the level of sugar in your blood over a 2-3 month period.
This is an important measure for diagnosing type 2 diabetes as well as understanding how well blood sugar levels are being controlled in people who have already been diagnosed with diabetes.
This test measures how much iron is in your blood with the aim of identifying iron deficiency anaemia or iron overload syndrome (haemochromatosis)
The symptoms of too much or too little iron can be similar - fatigue, muscle weakness, moodiness and difficulty concentrating.
A raised result can mean that you have iron overload syndrome, an inherited condition where your body stores too much iron, or that you are over-supplementing or that you have a liver condition.
A low result can mean that you are anaemic or are suffering from gastro-intestinal blood loss (or other blood loss). Anaemia is also very common in pregnant women.
Total iron binding capacity (TIBC) is a measure of the amount of iron that can be carried through the blood.
A raised TIBC result usually indicates iron deficiency whereas low TIBC can occur with iron overload syndrome (haemochromatosis).
Transferrin is made in the liver and is the major protein in the blood which binds to iron and transports it through the body.
Low transferrin saturation levels can indicate iron deficiency while high levels can indicate iron overload.
Ferritin is a protein which stores iron in your cells for your body to use later. Measuring ferritin levels gives us a good indication of the amount of iron stored in your body.
Low levels of ferritin can indicate anaemia which can be caused by excessive or chronic bleeding, poor absorption of iron or too little iron in the diet.
Raised ferritin levels can indicate iron overload syndrome (haemochromatosis) or any kind of liver damage. It is also a marker of infection and inflammation.
Triglycerides are a type of fat (lipid) that circulate in the blood. After you eat, the body converts excess calories into triglycerides which are then transported to cells to be stored as fat. Your body releases triglycerides to be used for energy.
Raised triglycerides are thought to be a risk factor for peripheral vascular disease (affecting the blood vessels which supply your arms and legs as well as organs below the stomach) as well as microvascular disease, affecting the tiny blood vessels around the heart.
Cholesterol is an essential body fat (lipid). It is necessary for building cell membranes and for producing a number of essential hormones. Cholesterol is manufactured in the liver and also comes from the food we eat. Elevated cholesterol is a risk factor for heart disease - the recommended level is below 5 mmol/L.
Cholesterol however is made up of both good (HDL) and bad (LDL) cholesterol so it is important to investigate a raised total cholesterol result to determine the cause. High levels of HDL cholesterol can cause a raised total cholesterol result but may actually be protective against heart disease.
HDL cholesterol (high density lipoprotein) removes cholesterol from the bloodstream and transports it to the liver where it is broken down and removed from the body in bile. HDL cholesterol is commonly known as "good cholesterol".
Raised levels are believed to be protective against heart disease, while low levels are associated with increased risk of a heart attack.
LDL cholesterol (low density lipoprotein) carries cholesterol, triglycerides and other fats to various tissues throughout the body. Too much LDL cholesterol, commonly called "bad cholesterol", can cause fatty deposits to accumulate on artery walls, potentially leading to atherosclerosis and heart disease.
Non-HDL cholesterol is calculated by subtracting your HDL cholesterol result from your total cholesterol. It therefore includes all the non-protective and potentially harmful cholesterol in your blood, not just the LDL cholesterol. As such, it is considered to be a better marker for cardiovascular risk than total cholesterol and LDL cholesterol. The recommended level of non-HDL cholesterol is below 4 mmol/L.
HDL cholesterol (high density lipoprotein) removes cholesterol from the bloodstream and transports it to the liver where it is broken down and removed from the body in bile. HDL cholesterol is commonly known as "good cholesterol" as raised levels are believed to be protective against heart disease, while low levels are associated with increased risk of a heart attack.
The ratio of total cholesterol to HDL is more indicative than a total cholesterol result alone to find out whether your cholesterol levels are healthy. This ratio should be as low as possible.
Omega 6 and omega 3 are essential fatty acids in the body responsible for controlling inflammation, brain development and regulating blood pressure. Omega 6 has a pro-inflammatory role in the body while omega 3 has an anti-inflammatory role. To control inflammation, ideally your omega 6/3 ratio should be around 2:1.
A high ratio increases the risk of chronic inflammation in the body, which is thought to be involved in the development of heart disease, cancer and autoimmune diseases. Eating more oily fish, flaxseeds as well as taking a daily supplement of cod liver or algae oil are effective ways to increase omega 3 levels and lower your ratio.
Vitamin B12 is important for production of red blood cells which carry oxygen around the body - low levels can cause anaemia with associated symptoms of lack of energy and fatigue. It is also important in metabolism and for the nervous system and prolonged lack of vitamin B12 may cause nerve damage. Vitamin B12 is almost entirely found in meat and animal food products.
Around 70% of vitamin B12 is bound to carrier proteins in your blood. This test measures the level of unbound or active B12 which is available for your cells.
A common reason for elevated B12 is over-supplementation. Raised levels of vitamin B12 may indicate a blood or liver disorder.
Low levels are seen in people with pernicious anaemia, an autoimmune disease which prevents the absorption of vitamin B12, or anyone who suffers from absorption problems such as the elderly, people with inflammatory bowel conditions and alcoholics. Vegetarians and vegans can also be low in vitamin B12, especially if they don't consume foods which have been fortified with vitamin B12 or take B12 supplements.
Folate is a water soluble vitamin which is needed by the body in your diet every day. It plays a role in DNA replication and protection, it's important for the production of red blood cells as well as in the prevention of neural tube defects in babies.
Low levels can indicate anaemia and can be implicated in raised homocysteine levels.
Although called a vitamin, vitamin D is actually a hormone which is activated by sunshine on your skin. Vitamin D is essential for bone strength as it helps your intestines absorb calcium. However, it is thought that vitamin D also plays an important role in immune function, as well as in many chronic diseases and mental health.
Many people in the UK do not produce enough Vitamin D, especially in the winter months with fewer daylight hours. It is now recommended that you get 10 - 15 minutes of unprotected sun exposure every day to ensure you are producing enough vitamin D. In winter months, if your levels are found to be low, you may wish to take a supplement.
Magnesium is an important mineral needed for proper muscle, nerve, and enzyme function. It helps the body make and use energy and aids the movement of electrolytes such as potassium and sodium into and out of cells.
The kidneys remove any excess magnesium from the body so developing raised magnesium levels (hypermagnesemia) is rare. However, those with kidney problems and those supplementing high amounts of magnesium may be at risk of developing hypermagnesemia.
A low magnesium level can be caused by poor nutrition and a high intake of alcohol. Magnesium is found in a variety of foods including nuts, leafy green vegetables, legumes and whole grains.
Cortisol is a stress hormone produced by the adrenal glands. It is vital to survival given its role in functions such as immunity, regulating blood pressure and releasing insulin for blood sugar maintenance.
Raised cortisol levels (Cushing's syndrome) can lead to rapid weight gain, especially around the waist, excessive body hair (in women) and loss of libido and erectile dysfunction (in men).
Low levels of cortisol (Addison's disease) can lead to fatigue, nausea, skin discolouration and low blood pressure.
