Kidney Check Plus

About this test

The kidneys are one of the most vital organs in your body. They remove all the waste products and excess water from your blood, turning them into urine for you pass safely.

A urine sample is examined under the microscope for blood cells, pus cells and casts (cells and mucous that collect in the kidney before passing into the urine). Protein may be detected where there is kidney disease or damage. 

Free liver function tests are also included, which check the level of bilirubin (a product of haemoglobin breakdown that is removed from the body) and various important enzymes which are vital for the liver to function correctly. A comprehensive cholesterol assessment is also included, with diabetes, gout and lipid tests establishing your risk factors.

Who is this test for?

These comprehensive tests are ideal for anyone looking for a general health assessment of their kidneys.

Important Information

Our tests are not a substitute for seeing your doctor, especially if you are suffering symptoms. Our doctors will interpret your results based on the information you have provided, but will not diagnose, consult or provide any treatment. You will be advised to see your doctor for any necessary follow-up action.

Tests Included

Kidney Function

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, weight, 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.

Sodium is both an electrolyte and a mineral. It helps regulate the water and electrolyte balance of the body and is important in the operation of nerves and muscles. Sodium levels in the blood are regulated by the kidneys. 

Excess sodium in the blood is often due to dehydration but can also indicate that the kidneys are not working properly. 

Too little sodium is often caused by fluid retention (oedema) or reflects loss due to vomiting, diarrhoea or excessive sweating. 

Liver Function

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.

Proteins

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.

Gout

Uric acid is a waste product from the digestion of protein. High levels can 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. 

Uric acid levels are best tested 6 weeks after symptoms appear as they may not be raised at the onset of a gout attack.

Diabetes

The random blood glucose test can be taken at any time of day. It measures the level of sugar in your blood and is an indicator of how well your body is metabolising sugars to store in your cells as glycogen.

As the test is random, the reference ranges are higher than that of a fasting sample as the test could have been performed shortly after eating.

Raised levels could indicate pre-diabetes or diabetes.

Iron Status

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.

Cholesterol Status

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.
