Your physician will perform a number of tests in order to establish a diagnosis.
These may include:
- Full blood count – this is to look at the level of substances such as platelets and haemoglobin in your blood.
- Urea & Electrolytes –this assesses your kidney function.
- Complement studies – to measure the levels of complement proteins C3 & C4 in your blood and to look for the presence of autoantibodies to complement proteins.
- Genetic testing – to see if you carry any of the known genetic faults associated with C3G.
- Urinalysis – looks for evidence of blood and protein in your urine that can indicate kidney damage.
- Ultrasound - a non-invasive scan that provides a general outline of the size and shape of your kidneys.
- Biopsy – a small piece of kidney tissue is removed and looked at under a microscope. This provides a more accurate picture of what may be causing the damage to the kidney.
