Dear Nealact User:
Thank you for purchasing the Nealact Lactate Meter Monitoring
System. This manual provides important information to help you to
use the system properly. Before using this product, please read the
following contents thoroughly and carefully.
If you have other questions regarding this product, please contact the
local customer service or place of purchase.
Intended Use
This system is intended for use outside the body (in vitro diagnostic
use) to quantitatively measure the lactate levels in whole blood. It is
for home use or for healthcare professional use. It should not be used
for diagnosis or screening of diseases.
The lactate test strip uses fresh capillary whole blood samples from
the fingertips, and from venous whole blood. Professionals may use
the test strips to test capillary and venous blood sample immediately;
home use is limited to capillary whole blood testing immediately.
Test Principle
Your system measures the amount of lactate in whole blood. The
lactate testing is based on the measurement of electrical current
generated by the reaction of lactate with the reagent of the strip. The
meter measures the current, calculates lactate level, and displays the
result. The strength of the current produced by the reaction depends
on the amount of lactate in the blood sample.

IMPORTANT SAFETY PRECAUTIONS
READ BEFORE USE
1. Use this device ONLY for the intended use described in this manual.
2. Do NOT use accessories which are not specified by the manufacturer.
3. Do NOT use the device if it is not working properly or if it is damaged.
