Lab Case 65 – Interpretation

A 61 year old female with evidence for sepsis, anaemia and dehydration


Microcytic hypochromic anaemia

Fe deficiency with elevated Ferritin

Obstructive picture on LFT without jaundice

normal electrolytes


Sepsis – ?liver /gallbladder source, other

(CRP was 325)

Dehydration – high urea

Fe deficiency anaemia with acute illness (Ferritin is an acute phase reactant)

Anaemia of chronic disorder:

Autoimmune – Crohn’s, SLE, RA, Ulcerative colitis

Cancer – Lymphoma, Hodgkin’s

Chronic kidney disease

Chronic Inflammation – Infective endocarditis, osteomyelitis, TB, HIV, Hepatitis C

So far, all the investigations in this lady have failed to reveal a cause for iron defiency and the elevated Ferritin was thought to be an acute phase reactant
