NOTE:
Dont use the following anticoagulants: EDTA, citrate, and oxalate, because they have a
great influence on test results for pH and electrolytes.
5.1.3 Collection Devices and Volume
Samples can be introduced into the system with the following devices: syringes and capillary
tubes. It is recommended that VITREX
®
Blood Gas Capillary Tubes with a minimum volume,
filled of 175μL (Article Number: 182413) should be used.
NOTE:
The system uses 110μL samples for analysis, and make sure it can aspirate enough
sample.
The minimum fill volume for a 1mL syringe is 200μL.
The minimum fill volume for a 2mL syringe is 800μL.
The minimum fill volume for a 5mL syringe is 1.5mL.
Dislodge bubbles from the syringe, and cover it as soon as the sample is collected.
Cork should never be used to cover the syringe.
A capillary tube should be filled to capacity and covered securely. Cork or clay should
never be used to cover the capillary tube.
5.1.4 Notes
Follow the notes below to ensure that test results are accurate:
1. Cover the sample device immediately after collection to prevent it from being
contaminated by air.
2. Mix blood samples thoroughly prior to sample introduction.
3. Make sure there are no clots in blood samples, or else the results will be inaccurate.
4. Perform the sample test immediately after its collection to get the most accurate
results. Measure samples for blood gases and Ca
++
within 10 minutes, and measure
samples for other analytes within 30 minutes.
5. Used sample devices are biohazardous waste, and should be handled abiding by
local regulatory guidelines.
