Entries in Biochemistry and Electrolytes
Staged by creatinine rise or urine output, classified as pre-renal, renal or post-renal
A memory aid for the stages of acute kidney injury and its causes.
Lipase is more sensitive and specific and stays raised longer
A memory aid for interpreting pancreatic enzymes.
Correct for albumin, then use the parathyroid hormone
A memory aid for correcting calcium and working out the cause of an abnormal result.
Below 1 per cent suggests prerenal; above 2 per cent suggests tubular injury
A memory aid for using FENa to distinguish prerenal from intrinsic renal failure.
Check osmolality, then volume status, then urine sodium
A memory aid for the stepwise assessment of hyponatraemia.
Transaminases versus alkaline phosphatase and gamma GT
A memory aid for distinguishing hepatitic from cholestatic liver tests.
Transaminases indicate hepatocellular injury; ALP and GGT indicate cholestasis
A memory aid for interpreting the liver enzyme pattern.
Measured minus calculated osmolality, raised by unmeasured osmoles
A memory aid for using the osmolar gap in poisoning.
Muscle injury from any cause, with rhabdomyolysis at the extreme
A memory aid for the causes of a raised creatine kinase.
Narrow therapeutic index drugs where effect cannot be measured directly
A memory aid for which drugs need level monitoring and when to sample.
A marker of myocardial injury, not of myocardial infarction
A memory aid for interpreting a raised troponin.
Most are for monitoring rather than diagnosis or screening
A memory aid for the common tumour markers and their uses.
Sodium, potassium, urea, creatinine and bicarbonate, read together
A memory aid for reading the urea and electrolytes systematically.
