There was some discussion about the very wide discrepancy between urea and
creatinine values seen in Case 70. Quite by chance this one turned up on my
desk a couple of weeks ago.
A 53 year old lady, seen by a Registrar (relatively junior member of the
Medical team) in the Renal Outpatient Clinic.
Clinical information on the request card is 'low albumin. Why?' Serum
results are
Sodium: 134 mmol/L
Potassium: 3.9 mmol/L
Bicarbonate: 28 mmol/L
Urea: 6.0 mmol/L
Creatinine: 378 umol/L (62 - 133)
Albumin: 20 g/L (35 - 49)
Globulins: 36 g/L (17 - 35)
Adjusted calcium: 2.59 mmol/L (2.10 - 2.55)
Phosphate: 0.77 mmol/L (0.81 - 1.45)
Uric acid: 192 umol/L (149 - 446)
Bilirubin: 14 umol/L (3 - 22)
Alkaline phosphatase: 135 IU/L (<126)
ALT: 10 IU/L (<56)
CRP: 37 mg/L (<8)
Free T4: 8.3 pmol/L (10 - 26)
TSH 41.1 mU/L (0.25 - 5.5)
The lady had been seen in Renal Outpatients three months earlier, when
fewer tests had been requested, but urea, creatinine, and albumin were very
similar to these values.
