Optional Testing Methods
Using Capillary Tubes
You may use capillary tubes to collect the blood from a fingerstick
and to dose the test strip. Use only CoaguChek Capillary
Tubes/Bulbs, Cat. No. 11621173001. Do not use glass capillary
tubes or capillary tubes that contain anticoagulants.
The following steps are optional to the fingerstick blood sample
instructions in the Preparing for a Test and Performing a Test
sections of this manual.
Out of Range Values
The CoaguChek XS PT test strips provide test results if the INR
value is between 0.8 and 8.0. If the result falls outside of this
range, the meter displays < (less than) 0.8 or > (greater than) 8.0.
If the meter indicates an out-of-range value, refer to the test strip
package insert and repeat the test.
In rare cases, Error Message 7 can occur in patients with long
coagulation times (> 8 INR). If this error message appears again
when the test is repeated, the result must be checked using
another method.
