Table 1

Initial results of serum laboratory investigations.

Study	Result	Normal range (units)
C-reactive protein	88.1^H	<3 (mg/L)
Erythrocyte sedimentation rate	95^H	<21 (mm/h)
White cell count	7.7	4-11 (×10^9/L)
Neutrophils	6.2	2-8 (×10^9/L)
Platelets	302	150-450 (×10^9/L)
Hemoglobin	105^L	130-180 (g/L)
Mean corpuscular volume	91	80-99 (fL)
Creatinine	111^H	60-110 (μmol/L)
Urea	7.5	3-9 (mmol/L)
Estimated glomerular filtration rate	62	>59 (mL/min/1.73m^2)
Bicarbonate	28	22-32 (mmol/L)
Albumin	28^L	35-50 (g/L)
Corrected calcium	2.47	2.15-2.55 (mmol/L)
Phosphate	1.05	0.75-1.50 (mmol/L)
Thyroid-stimulating hormone	0.79	0.50-5.00 (mIU/L)
Free thyroxine	22.4	9-25 (pmol/L)

H: high; L: low. Initial full blood count and biochemistry revealed elevated inflammatory markers such as C-reactive protein and erythrocyte sedimentation rate. Other abnormalities included mild renal impairment, hypoalbuminemia, and normocytic anemia, all likely secondary to subacute infection. Thyroid function was normal.
