The renal team see the patient and take over his care. You enquire after the patient a few days later and hear that he has undergone a renal biopsy. This shows a crescentic glomerulonephritis, but immunofluoresence on the biopsy was negative.
Which of these blood tests do you think will be positive? (Hover over 'select' to see if you're right)
| 1. Anti-GBM | select | |
| 2. Complement | select | |
| 3. ANA | select | |
| 4. Anti-ds DNA | select | |
| 5. ANCA | select |
