Interference Studies
Interference studies were performed according to CLSI
Document EP7-A2. The following substances have not
been found to interfere with the HemoCue WBC system.
The highest concentration or percentages tested is
referred to in brackets.
Acetaminophen (20 mg/dL), ascorbic acid (6 mg/dL),
ibuprofen (50 mg/dL), caffeine (308 µmol/L), creatinine/
urea (30 mg/dL/500 mg/dL), salicylic acid (60 mg/dL),
tetracycline (30 mg/dL), unconjugated bilirubin
(342 µmol/L), conjugated bilirubin (380 µmol/L), dex-
tran 40 (30 g/L), osmolality (167 mmol/L), HbCO (30 %),
methemoglobin (50 %), thrombocytes (2000 x10
lipemia (intralipid 3100 mg/L) which corresponds to
triglycerides (approximately 10.5 mmol/L), hemoglobin
(30–250 g/L), reticylocytes (258 x10
leukocytes and platelet clumping have not been found
to interfere. pH values between 6.8–8.0 do not interfere
with the system.

Essential Performance
The HemoCue WBC system is an In-Vitro diagnostic
system designed for quantitative determination of white
g/L), blood cells (WBC) in capillary or venous whole blood.

HemoCue WBC Analyzer
The HemoCue systems are intended for use in an electro-
magnetic environment in which radiated RF disturbances
are controlled. The customer or the user of HemoCue
systems can help prevent electromagnetic interference
by maintaining a minimum distance between portable
and RF communications equipment (transmitters) and
HemoCue systems as recommended below, according
to the maximum output power of the communications
equipment.
