Other Important Information for Healthcare
Professionals:
e most accurate results come from using fresh,
capillary whole blood from the fingertip or forearm.
Venous whole blood drawn into EDTA (purple top
tube) or heparin (green top tube) may be used. Mix
tube contents gently before using.
When comparing results between TRUEresult and a
laboratory system, perform a TRUEresult blood test
within 30 minutes of laboratory test. Results from the
TRUEresult System are considered accurate if within
20% of laboratory results.

If the patient has recently
eaten, fingerstick results from the TRUEresult System
can be up to 70 mg/dL higher than venous laboratory
results.

Health Related Information DO NOT perform
capillary blood glucose testing on critically ill
patients. Capillary blood glucose levels in critically ill
patients with reduced peripheral blood ow may not
reect the true physiological state. Reduced peripheral
blood ow may result from the following conditions
(for example):

• shock
• severe hypotension
• severe dehydration
• hyperglycemia with hyperosmolarity, with or
without ketosis.
