5 Detecting and investigating AKI in patients with suspected or confirmed COVID-19

5.1 Detect acute kidney injury (AKI) using NHS England's AKI algorithm or any of the following criteria:

  • an increase in serum creatinine of 26 micromol/litre or more in 48 hours

  • an increase of 50% or more in serum creatinine known or presumed to have occurred in the past 7 days

  • a fall in urine output to less than 0.5 ml/kg/hour for more than 6 hours.

5.2 Do urinalysis for blood, protein and glucose to help identify the cause of AKI. Record the results and take action if these are abnormal (including referral if needed; see section 8). Determine the preferred method of urinalysis locally during the COVID‑19 pandemic.

5.3 Do imaging if urinary tract obstruction is suspected.
