​​​Our specialized clinic investigates and treats patients with glomerulonephritis who have been referred by a nephrologist or a family doctor who has tested for and found large amounts of protein and/or blood in the patient's urine – this is usually found on a timed urine collection and albumin-creatinine ratio in the urine or urinalysis.


Urgent Referral

If your patient needs immediate or urgent care, because of rapidly progressive kidney disease suspected to be related to primary or secondary glomerulonephritis (GN), contact the office of Dr. Daniel Cattran, who will triage the patient to a Glomerulonephritis Clinic physician. Contact Dr. Daniel Cattran by phone at 416 340 4187 or by fax at 416 340 3714.​

All types of GN associated with deteriorating renal function ­are considered urgent. Deteriorating renal function may be documented by a rapidly rising creatinine and usually is associated with proteinuria, either with or without systemic features.
