Point-of-care (POC) testing offers several advantages over traditional laboratory tests. It needs smaller blood samples, works faster, and makes patients happier. This leads to better blood sugar control and care. POC testing is especially important for hospital patients. It helps lower the risks and deaths associated with poor blood sugar management.
Learning about blood glucose testing helps you manage your health better. You can work with your healthcare team to manage your blood sugar levels effectively.
How Glucose POC Test Works
Glucose point-of-care (POC) tests enable individuals with diabetes to quickly and accurately check their blood sugar levels. They use enzymes to measure glucose in the blood. For example, the ACCU-CHEK Inform II system utilizes a special enzyme to convert glucose into a substance that generates an electrical current.
This system is set up using blood samples and gives results that match those from a lab. This ensures the readings are reliable and consistent.
To use a glucose POC test, you need to put a small blood drop on a test strip. The strip has special chemicals that react with the glucose. This reaction creates a current that the meter measures, showing your blood sugar level.
This entire process is fast, providing you with quick feedback on your blood sugar status.
One significant advantage of glucose POC testing is that it provides results comparable to those of lab tests. This means doctors can trust the readings and make more informed decisions for their patients. This helps improve diabetes care and management.
Glucose POC testing is crucial for diabetes management. It allows people to check their blood sugar frequently and make informed choices about their health. Understanding how these tests work helps people with diabetes appreciate the importance of this technology in maintaining their health.

| Hypoglycemic threshold | Less than 70 mg/dl |
| Hyperglycemic threshold | More than 130 mg/dl |
| Glucose concentration decline in whole blood samples | Approximately 5% per hour, up to 40% in 3 hours |
“Accurate blood sugar monitoring starts with proper sample collection. Following the right techniques is crucial for obtaining reliable and meaningful test results.”
Step-by-Step Testing Procedure
Using a glucometer for a point-of-care (POC) glucose test is easy. It involves several important steps. Before starting, make sure you follow good self-monitoring of blood glucose and diabetes management practices. Here’s how to do it step by step:
Pre-Testing Preparation
First, turn on your glucometer and enter your or the patient’s ID. Then, put the right test strip into the meter. The Accu-Chek Advantage monitor needs specific strips.
Sample Application Method
Next, get a small blood sample, usually from your fingertip. Carefully apply the blood to the test strip. Ensure it’s the correct amount, between 9 and 50 microliters, for the Accu-Chek Advantage monitor.
Result Interpretation Guidelines
The glucometer will show your blood glucose level in milligrams per deciliter (mg/dL). It’s key to understand the result based on the patient’s health and any factors that might have affected the test. Maintaining blood glucose levels between 4 and 7 mmol/L (72 and 126 mg/dL) is crucial for managing diabetes and preventing complications.
By following these steps and understanding the results, you can accurately monitor your blood glucose levels. This helps in effective diabetes management.
Quality Control Measures
Maintaining accurate diabetes technology and blood sugar monitoring is crucial in healthcare. To keep things running smoothly, healthcare places focus on quality control for glucose testing.
The Glucose Whole Blood testing procedure for the Roche ACCU-CHEK Inform II meter was updated in 2013 and 2017. It requires nursing staff to pass competency tests within a year. They must document their training and testing.
The American Diabetes Association backs Point of Care Testing (POCT) for those with diabetes in hospitals. The system utilizes venous blood with varying glucose levels to achieve plasma-like results. These results are traceable to a NIST standard.
Quality control is vital in the testing process. Facilities must run quality control solutions for glucose levels every 24 hours. In low-volume areas, this can be done every week, typically on patient testing days.
| Metric | Allowable Error |
|---|---|
| Glucose >100 mg/dl | ±20% |
| Glucose ≤100 mg/dl | ±10 mg/dl |
| Glucose >76 mg/dl | ±20% (95% of results) |
| Glucose ≤76 mg/dl | ±15 mg/dl |
Testing can use capillary, venous, arterial, or neonatal whole blood, with specific anticoagulant needs. Each test strip box has a unique code for the ACCU-CHEK Inform II system. The system doesn’t need calibration by the operator, as the POCT technologist uploads the code.
The meter must be used in patient areas, and the operator ID must be scanned for each test. Patient ID is entered using barcoded wristbands or a keypad in some places. Keeping QC results documented is crucial for testing reliability and traceability.
PoCT often involves checking cartridges/strips on delivery and running a QA sample monthly. New point of care analyzers for clinical staff have brought challenges in applying traditional QC systems.
Modern PoCT analyzers are seen as systems with an analyzer and a cartridge/strip component. This affects which parts are tested during QC runs. Full-size analyzers from labs need daily QC samples, regular QA samples, and strict maintenance for effective QC.
Cartridge-based systems face challenges due to the test cartridge’s role in the process. Strip-based instruments, meant for direct consumer use, require stricter QC practices because of their simplicity and calibration by lot.
Understanding Test Results and Reference Ranges
Checking your blood sugar levels is crucial for managing diabetes and maintaining good health. Knowing what’s normal and what’s not helps you understand your test results. This way, you can act quickly when needed.
Normal Glucose Ranges
People without diabetes usually have fasting blood glucose levels between 70 and 99 mg/dL (3.9 and 5.5 mmol/L). Levels between 50 and 70 mg/dL (2.8 to 3.9 mmol/L) are also okay. If your levels are 100 to 125 mg/dL (5.6 to 6.9 mmol/L), you might have prediabetes. This means you could get type 2 diabetes in 5 to 10 years.
Fasting blood glucose of 126 mg/dL (7.0 mmol/L) or higher on several tests means you have diabetes.
Type 2 diabetes happens when your pancreas doesn’t make enough insulin or your body can’t use it well. Type 1 diabetes is when your body attacks and destroys insulin-making cells in your pancreas. Gestational diabetes happens in some pregnant women between 24 and 28 weeks and goes away after birth.
Critical Values and Action Limits
Values below 70 mg/dL (3.9 mmol/L) or above 300 mg/dL (16.7 mmol/L) require prompt action, but this can vary. Knowing these ranges is crucial for both healthcare providers and individuals to avoid serious problems.
Approximately 1 in 20 healthy individuals may have blood glucose levels outside the normal range. Other health issues, such as thyroid problems or stress, can also impact blood sugar levels. Low blood sugar (hypoglycemia) can happen for many reasons, including too much insulin.
Venous blood glucose tests take 1 or 2 days, while capillary tests give results in seconds. However, blood tests can have risks, such as bleeding or infection.
Knowing normal glucose ranges and critical values helps you monitor your blood sugar effectively. This way, you can take the right steps to stay healthy.
Common Errors and Troubleshooting
Dealing with diabetes technology can be challenging, especially when it comes to blood sugar monitoring. Issues like not enough sample or expired test strips can mess up your readings. This can affect how well you manage your diabetes.
