Critically unwell male patient.

On 'aggressive' CVVHDF with Albumin replacement.

 
submitted D.Compton
Submitted as HAGMA secondary (in part) to Albumin

However,

  • rise in AG is moderate ≈ 23 and consistent with:
    • level of renal impairment
    • modest fall in HCO3-
    • this alone doesn't suggest presence of another major acid anion
  • grossly elevated globulins also present?
    • albumin products in AU are >96% albumin
    • generous albumin replacement would not be expected to cause this rise
    • if GG (+) then this would artificially lower the observed AG
    • this may explain
      • severity of clinical picture, c.f. observed AG
      • origin of clinical picture, e.g. underlying MM or hepatic disease
