A

Albumin

Albumin is the main protein found in our blood.1

Albuminuria

When a person’s urine contains a higher-than-normal amount of albumin (a protein typically found in the blood).1

Antibody

A protein made by the immune system to protect the body from foreign substances such as bacteria or viruses.1

B

Biopsy

A procedure in which a needle is used to extract small pieces of tissue for examination with different types of microscopes, each of which shows a different aspect of the tissue.2

Brain fog

Loss of mental sharpness and fuzzy thinking.3

C

Chronic disease

When a disease lasts for at least 3 months (but is usually lifelong) and tends to get worse over time.4,5

Computed tomography (CT)

A series of x-ray images taken from different angles and processed using computer software. CT scans give a more detailed picture of inside the body than single x-rays do.6

Creatinine

A waste product that’s naturally produced by our muscles and can be used by doctors to estimate how well the kidneys are working.7

D

Dialysis

When a machine outside of your body filters your blood for you to remove waste products and excess fluid.8

E

Estimated glomerular filtration rate (eGFR)

An estimate of how well your kidneys remove waste products from your blood.9

F

Fatigue

Extreme tiredness with very little motivation or energy.10

Flank

The sides of the abdomen and back, between the lower ribs and hips, where the kidneys are located.11,12

G

Genetic testing

A way to detect changes in genes that can cause health problems.13

Glomerular disease

A type of kidney disease caused by damage to the glomeruli (the tiny filters within the kidney that clean our blood).2

Glomeruli

Tiny filters within the kidney that clean our blood.2

H

Haematuria

When there is blood in your urine. If the blood is visible to the naked eye, it is called macrohaematuria. If not, it is called microhaematuria.14

Hypertension

When the pressure in your blood vessels is too high.15

I

IgA nephropathy

A type of glomerular disease that occurs when an abnormal form of an antibody called immunoglobulin A (IgA) builds up in the kidneys, causing inflammation that damages kidney tissues.1

Immunoglobulin A (IgA)

A type of antibody.1

Infection

When viruses, bacteria, or other microbes enter your body and begin to multiply.16

Inflammation

The body’s immune system’s response to an irritant, such as bacteria or a foreign object (like a splinter).17

K

Kidney

Two bean-shaped organs, each about the size of a fist, located just below the rib cage (the flank), one on each side of your spine.11,12

Kidney disease

When your kidneys are damaged and can’t filter blood the way they are supposed to.18

N

Nephrotic range proteinuria

When the level of protein in a patient’s blood is extremely high, which is generally considered to be above 3 g per day.2,19

Nephrotic syndrome

A group of symptoms associated with kidney damage such as large amounts of protein in your urine (nephrotic range proteinuria), low levels of protein in your blood and oedema.20

O

Oedema

Swelling caused by too much fluid trapped in the body's tissues, usually in the legs and feet.21

P

Proteinuria

When protein leaks into the urine, causing foamy urine.22 It is also called albuminuria.22

R

Rare disease

A disease that affects very few patients.23,24

Renal imaging

A non-invasive procedure that uses ultrasound or computed tomography (CT) to scan the kidneys and check that they are a normal shape and size.2

T

Toxic

When something is poisonous or harmful to the body, often causing unwanted side effects.25

Transplant

When tissue or an organ is transferred from one area of a person’s body to another, or from one person to another.26

U

Ultrasound

A procedure that uses sound waves to look at tissues and organs inside the body.27

Urea nitrogen

Urea nitrogen is a waste product that is naturally produced after the liver breaks down proteins.7 When the kidneys aren’t working well, the level of urea nitrogen in the blood goes up, indicating that the kidneys aren’t removing it as efficiently as they should.7 Doctors use it to estimate how well the kidneys are working.7

Urinalysis

A urine test used to detect and manage a wide range of disorders, including kidney disease.28
