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.
