Blood gas syringes and capillary tubes 

Meet your blood sampling needs with our samplers, designed to facilitate reliable test results 

Syringes and capillary tubes are designed to reduce the risk of preanalytical errors

As blood gas specialists, we’re empowered to advance acute care diagnostics. From reducing the risk of preanalytical errors to providing a reliable blood gas test result, we ensure constant focus on supporting you and your patients.

Radiometer capillary tubes, aspirating and self-fill blood gas syringes are designed with various features that are intended to reduce the risk of preanalytical errors.



Furthermore, our products support the Patient Blood Management which is an evidence-based approach to optimizing the care of patients’ blood. This includes opportunities to minimize blood loss and avoid the inappropriate use of blood.

We’re committed to empowering you to take control of the blood sampling process. Discover a blood gas syringe or capillary tube that supports your blood sampling workflow.

Aspirating syringe

Pre-barcoded aspirating syringe helps ensure correct patient-sample identification every time when using with a Radiometer blood gas analyzer with 1st Automatic.


Self-fill syringe

safePICO self-fill syringe is equiped with an integrated mixing ball and automatic mixing which enhances analytical quality through standardized mixing, without causing hemolysis.


Capillary tube

Our capillary tube is used for low-volume blood gas sampling, mainly on neonates.

Radiometer - specialists by bloodSpecialists by blood

The history of Radiometer as we know it today began in 1954 when Radiometer developed the world’s first commercially available blood gas analyzer. Since then, we have refined our blood gas testing knowledge and experience and continue to advance our acute care diagnostic solutions.

Minimizing preanalytical errors in blood gas testing

Hemolysis in blood samples

Learn more

 

Reducing hemolysis in blood samples

Hemolysis is the rupture of the red blood cells, and may happen during sample collection and the following process. The rupture causes the intracellular components of the destroyed red blood cells to be mixed with the plasma. Some of the components, e.g., potassium (K+), are more concentrated in the intracellular compartment than in the plasma phase. Therefore, the reported potassium result will be falsely high.

Clots in blood samples

Clots in blood samples

Clots in the sample can potentially lead to blocking of the sample pathway on the analyzer and to inaccurate values.

Clots can be caused by:
  • Too low concentration of heparin in the sample
  • Lack of or insufficient mixing of the sample immediately after it has been collected

Air bubbles in the sample

Air bubbles in the sample

Room air contamination of a blood gas sample may alter the values of the sample so that it no longer represents patient's status.

To minimize errors:

  • Visually inspect the sample for air bubbles
  • Expel any bubbles by gently tapping the sides of the syringe right after sampling and before mixing
  • Use arterial blood gas syringes with tip caps that are vented and will allow you to expel air and seal the syringe without getting in contact with blood

Needlestick injuries

Needlestick injuries

Needlestick injury and unwanted contact with patient blood are daily risks for operators collecting blood gas samples.

To minimize risks

  • If available, use a safety device that limits the risk of contact with patient blood
  • Do not recap needles
  • If available, use a needle shield protection device when removal of needles
  • Ensure a dedicated procedure for operator safety is established and followed in your facility

Mix-up of patient samples

Incorrect or missing patient and sample IDs are some of the most frequent preanalytical errors occurring in blood gas testing with significant consequences for patient care, for healthcare management and for increasing costs that are often unaccounted for.
