What Is Blood Analysis, and What Is the epoc Blood Analysis Testing System?
Whether in a traditional environment or point-of-care scenario, blood analysis testing is an important diagnostic tool that measures various aspects of a single blood sample, including oxygen and carbon dioxide levels and pH. These tests are often ordered as a way to evaluate a patient for potential respiratory or breathing-related problems, among others.
Blood analysis can be performed in a laboratory with conventional large laboratory instruments or patient side at the point of care. The epoc Blood Analysis System developed by Siemens Healthineers—the primary focus of this article—is a handheld point of care blood analysis system.
What Is Point of Care Testing for Blood Gases Used For?
Point of care blood gas testing is a versatile tool that doctors and other medical professionals might order to help determine the cause for a patient’s respiratory or metabolic symptoms, among others.
One of the most common use cases for epoc blood analysis relates to blood gas testing, working with patients who may be experiencing symptoms related to respiratory conditions. This might include…
- Evaluating a patient’s oxygen and carbon dioxide levels to learn whether their lungs are effectively delivering oxygen into their blood (and extracting carbon dioxide from it); this can help diagnose chronic respiratory conditions like COPD or asthma.
- Monitoring certain acute respiratory conditions reported by patients, so that appropriate management and treatment options can be considered for potential pneumonia, among other disorders.
- Determining whether a patient is experiencing respiratory failure, including the condition’s severity, in order to develop the appropriate treatment plan.
Blood gas testing is also effective as a means for diagnosing and assessing the severity of certain metabolic conditions—like metabolic acidosis or alkalosis—based on patient symptoms.
While the diagnosis of respiratory and metabolic conditions are the primary use cases for point of care blood analysis, those are not the only applications. Point of care blood analysis may also provide valuable metabolite and electrolyte testing. With this full menu of critical analytes, it also may be ordered in certain critical or emergency situations (like sepsis or cardiac arrest), as part of post-operative or intensive care monitoring, or in the course of providing neonatal and pediatric care.
What Does epoc Test For?
With a single test card, the Siemens Healthineers epoc blood gas analyzer accurately evaluates patients’ blood gas, electrolyte, and metabolite (BGEM) levels by measuring 13 different analytes. Unlike other testing solutions, you won’t need multiple epoc test cards for a single, comprehensive analysis. The epoc test menu includes the following parameters:
- pH
- Partial pressure of carbon dioxide (pCO2)
- Partial pressure of oxygen (pO2)
- Total carbon dioxide (TCO2)
- Sodium
- Potassium
- Ionized Calcium
- Chloride
- Hematocrit
- Glucose
- Lactate
- Blood urea nitrogen (BUN)
- Creatinine
What Are the Main Benefits or Advantages of the epoc Testing System?
Using a handheld solution like the epoc System provides many advantages over its alternatives—including, among others:
- Quicker Turnaround Times: When it comes to clinical decision-making, the ability to achieve accurate results with unmatched turnaround times can be the difference between timely interventions and the potential for patients’ symptoms to worsen in the interim. That’s why handheld, portable solutions like the epoc blood gas testing system are such powerful instruments for clinicians. The epoc System is easy to use and provides accurate results in less time than other diagnostic alternatives.
- Increased Operational Efficiency: In addition to providing quicker turnaround times on a case-by-case basis, integrating the epoc testing system into clinical workflows and procedures increases efficiency on a larger scale. The ability to collect and process samples right at the patient’s bedside saves valuable time while eliminating the need to transport the sample to a lab facility (which is inefficient and can lead to problems with the integrity of collected samples).
- Reliable Accuracy and Quality: While some providers might be skeptical that a handheld, efficient solution like the epoc testing system can be as accurate as traditional methodologies, it does provide lab-accurate results. You can learn more by reviewing the Summary of Analytical Methods and Performance resource, which offers a point-by-point comparison of testing accuracy for each tested analyte.
- IT Security: The portability of handheld blood analysis systems—enabled by wireless connections—doesn’t just provide efficiency; it also improves security. The epoc System easily integrates with intuitive data management software (DMS) and hospital information systems (HIS), enabling remote management and quality control. This empowers providers with proactive, secure solutions that protect patient information as well as facilities’ data and systems—all without compromising speed or security.

What Is the epoc Testing Process?
The basic epoc testing process consists of 4 simple steps, described below.
- Initiate the Test
Setup is easy! When you need to perform a test, begin by detaching the Host from its Reader and scanning your credentials to authorize access to the system. On returning the Host to the Reader, the system will perform a brief series of internal checks to verify system readiness and functionality.
- Insert the Test Card and Calibrate the System
When prompted, insert the Test Card to initiate the system calibration process, which includes checking the Test Card’s expiration date (and replacing it with a valid, new Test Card if necessary). The calibration process takes around 3 minutes, and effectively mitigates potential errors that could lead to the loss of a valuable sample.
Once the Test Card has been verified and the epoc testing system has been calibrated, the sample can be drawn using either a syringe or epoc Care-Fill™ Capillary Tube.
In order to protect patient safety and the accuracy of results, the system includes additional features including patient ID verification, automated quality assurance, and simple, efficient workflows. The operator can add to the collected patient information through a series of dropdown menus for inputting settings related to the patient, sample type, and scope of testing.
- Inject the Sample
When prompted, inject the sample into the Test Card. This process is guided by visual prompts to ensure proper technique. Once the sample has been added, the system begins its analysis. Within a minute, results will be displayed.
- Process the Results
Upon completion of testing, the operator can view the results, including color-coding to indicate critical, out of range, and normal values (if using the epoc NXS Host, in which case the operator will also be prompted to address “critical” results). Despite the quick turnaround time, results provided by the epoc testing system are no less precise than traditional methods.
What Type of Sample Can Be Used on the epoc Testing System?
The epoc Blood Analysis System can utilize several different types of samples, including fresh whole blood and/or fresh whole heparinized blood from arterial, venous, or capillary sources. Regardless of the source type, once a sample is introduced to the test card (more on this below), it is simultaneously processed and analyzed by the epoc machine.
How Much Blood Do You Need for epoc Blood Analysis?
Another advantage of the epoc Blood Analysis System is that it requires a smaller sample size than its alternatives—epoc’s flexible and efficient sample processing means fewer redraws (and fewer delays in treatment). When using the epoc System, you can draw the blood using either a syringe (which requires at least 92 microliters) or epoc Care-Fill™ Capillary Tube (which only requires a 90-microliter sample).
How Long Does the epoc Test Take to Return Results?
The epoc blood analysis testing system returns lab-accurate results within a minute after the sample is introduced to the test card.
Is the epoc Blood Analysis System Price Worth It?
Thanks to its ease of use, efficiency, and ability to deliver lab-accurate results in around a minute from sample application, the epoc blood analysis is well worth the investment. Let’s look at a few of its prime differentiators (vs. more traditional testing systems).
Work Smarter, Not Harder
The epoc testing system makes bedside testing a viable and accessible option across a number of different clinical settings. With the epoc System, providers can streamline and consolidate workflows and use a single test card to measure 13 analytes (as well as 18 additional values).
Prioritize Efficiency (without Compromising Accuracy)
