Kidney Function

Kidney Function

Your kidneys play an important role in maintaining general health and wellbeing. They filter your blood, ensure fluid balance, help regulate blood pressure and facilitate the production of urine (which removes waste from your body). Your kidney function test is a panel of three bloods tests which measure the amount of sodium (salt) and two chemical waste products (urea and creatinine) in the blood. Additionally there is a calculation of your eGFR which is a useful way to check for reduced kidney function.

Overview

Your results have been given a green flag as they are all within the recommended ranges. You can read more about what this means below.

Creatinine

87

umol/L

<= 65

66 - 112

113 - 130

>= 131

umol/L

Creatinine

Your creatinine result has been given a green flag as it is within the recommended range. Creatinine is a chemical waste product of muscle metabolism, which is removed from the blood by the kidneys. Common causes of a raised creatinine level include high muscle mass, high protein intake, impaired kidney function and some medications. Common causes of a decreased creatinine level in the blood include older age, reduced muscle mass, following a vegetarian diet or malnutrition. Creatinine levels are also usually lower in females than males.

eGFR

>90

mL/min

<= 59

60 - 89

>= 90

mL/min

eGFR

Your eGFR (estimated glomerular filtration rate) result has been given a green flag as it is within the recommended range. The eGFR is a measure of how much blood is being 'cleaned' by your kidneys every minute. Therefore a higher figure demonstrates kidneys that are working well, and lower figures demonstrate kidneys that aren't working as efficiently. The eGFR is estimated using your creatinine level and also takes into account your age and sex. The eGFR test is a good way to check for reduced kidney function, especially in conjunction with a urinalysis (urine) test. We now recommend that your eGFR is measured with us on an annual basis – especially if you are on blood pressure treatment or have diabetes – in order to enable you to keep an eye on your kidney function.

Sodium

140

mmol/L

<= 126

127 - 134

135 - 145

146 - 150

>= 151

mmol/L

Sodium

Your sodium result has been given a green flag as it is within the recommended range. Sodium is found in the blood in small levels, where it helps regulate blood pressure and fluid balance in the body. Common causes of a reduced sodium level (hyponatraemia) include pneumonia, brain haemorrhages, being elderly and certain medications (such as thiazide diuretics). Common causes of a raised sodium level (hypernatraemia) include excessive fluid loss (from sweating, vomiting, diarrhoea or burns), uncontrolled diabetes and some endocrine syndromes.

Maintaining a healthy weight for your height and ensuring that you stay well hydrated during periods of illness will reduce your risk of developing an imbalance in your sodium levels.

Urea

4.3

mmol/L

<= 1.6

1.7 - 8.3

8.4 - 11.0

>= 11.1

mmol/L

Urea

Your urea result has been given a green flag as it is within the recommended range. Urea is the breakdown product of proteins, which is removed from the body by the kidneys as urine. Diseases affecting the kidneys or liver can cause abnormal urea levels in the blood. Common causes of a raised urea level include dehydration, a high protein diet, gastro-intestinal (gut) haemorrhage, renal failure or urinary outflow obstruction. Causes of a decreased urea level include chronic liver disease, pregnancy or malnutrition.
