Knowing how to keep a record of diabetes screening results is one of the most empowering steps you can take for your long-term health. Whether you have recently undergone a diabetes blood test for the first time or you monitor your indicators regularly, maintaining an organised log of your results helps you recognise patterns, engage more meaningfully with healthcare professionals, and take ownership of your wellbeing.
In the UK, an estimated 4.3 million people are living with diabetes, and a further 850,000 are estimated to be undiagnosed. Routine diabetes screening — especially tracking key biomarkers over time — plays an important role in early awareness and ongoing health management.
What Is Diabetes Screening and Why Does Record-Keeping Matter?
Diabetes screening is a preventive health process involving blood tests that measure how the body processes glucose. It is used to identify whether blood sugar levels fall within a healthy range, or whether further assessment may be advisable. Screening does not diagnose or treat — it provides measurable data that can support informed conversations with appropriate healthcare providers.
Keeping a personal record of your diabetes screening results means you can:
- Track changes in key biomarkers over weeks, months, or years
- Identify trends that may warrant further attention
- Provide accurate information to any healthcare professional you consult
- Feel more confident and informed about your own health data
Practical Insight: Record-keeping is not about creating anxiety. It is about building a clear, factual picture of your health over time — one that belongs to you.
Key Biomarkers Measured in Diabetes Screening
Understanding what is being measured helps you record results meaningfully. The core biomarkers typically included in a diabetes screen are:
| Biomarker | What It Measures | Standard UK Reference Range |
|---|---|---|
| HbA1c | Average blood glucose over 2–3 months | Below 42 mmol/mol (non-diabetic) |
| Fasting Glucose | Blood sugar after an overnight fast | 3.9–5.5 mmol/L (normal) |
| Random Glucose | Blood sugar at any point in time | Below 7.8 mmol/L (typical) |
| Fasting Insulin | Insulin levels when fasting | Varies by laboratory |
HbA1c (Glycated Haemoglobin): This is widely considered the most informative long-term marker for blood sugar control. A result between 42–47 mmol/mol may suggest prediabetes; 48 mmol/mol or above can indicate diabetes. These are reference ranges — individual clinical context always matters.
Fasting Glucose: Elevated fasting glucose can sometimes highlight how the body manages sugar between meals. A value between 5.6–6.9 mmol/L may indicate impaired fasting glucose.
Random Glucose: Taken at any time of day, this reading provides a snapshot rather than a pattern. It is most useful when reviewed alongside other markers.
Practical Insight: No single result tells the whole story. A pattern of results over time is far more informative than any individual reading.
Who Should Consider Regular Diabetes Screening?
Certain individuals may benefit from more consistent monitoring of diabetes-related blood markers. You may wish to consider regular screening if you:
- Are aged 45 or over
- Have a family history of type 2 diabetes
- Are living with overweight or obesity (BMI over 25)
- Have previously received a prediabetes result
- Experience fatigue, increased thirst, or frequent urination
- Are of South Asian, African-Caribbean, or Black African descent (groups with higher statistical risk in the UK)
- Have polycystic ovary syndrome (PCOS)
- Had gestational diabetes during a previous pregnancy
If you are unsure whether you fall into a higher-risk group, a private health screening in London can provide baseline data to start tracking from.
How Often Should You Screen for Diabetes?
Frequency of screening is not one-size-fits-all and will depend on individual circumstances. As a general guide:
- Low risk, no symptoms: Every 1–3 years may be sufficient to establish a baseline
- Prediabetes range: Every 6–12 months is commonly suggested to monitor progression or improvement
- Post-gestational diabetes: Annually is often recommended
- High-risk individuals: More frequent testing may be appropriate — discuss with a relevant healthcare professional
In a busy city like London, accessing a walk-in blood test appointment without a long wait makes maintaining a regular screening schedule far more achievable for working individuals and families alike.
How to Keep a Record of Diabetes Screening Results: A Practical Guide
Once you have your results, the way you store and organise them is just as important as the results themselves.
Step 1 – Request a Printed or Digital Copy of Every Result
Always ask for a copy of your results at the time of testing. Reputable private clinics will issue a full written report. Keep both a digital copy (cloud-stored or emailed) and a physical backup where possible.
Step 2 – Create a Simple Tracking Log
You do not need specialist software. A basic spreadsheet or even a paper notebook works well. Include:
- Date of test
- Type of test (HbA1c, fasting glucose, etc.)
- Result value and unit (mmol/mol or mmol/L)
- Reference range provided by the lab
- Name of the clinic or laboratory
- Any preparation notes (fasted, time of last meal, etc.)
Step 3 – Note Contextual Information
Blood glucose results can be influenced by illness, stress, diet changes, or medication. Note any relevant context alongside each result. This makes your records far more useful when reviewed over time.
Step 4 – Use a Timeline View
Plotting results on a simple graph or timeline — even by hand — can help you visualise changes more clearly than a list of numbers.
Step 5 – Review Results With an Appropriate Professional
Your records are most valuable when shared with a qualified healthcare provider who can contextualise them within your overall health picture. A nurse-led clinic can provide testing and report results, but ongoing clinical interpretation should involve appropriate medical support.
Practical Insight: Consistent record-keeping, even for just two or three testing cycles, can reveal meaningful patterns that might otherwise go unnoticed.
What Do Diabetes Screening Results Mean?
Results from a diabetes screen may suggest a range of possibilities. They do not diagnose you — they provide data points.
- Within normal range: Can suggest blood glucose is currently being managed effectively by the body
- Borderline or prediabetes range: May indicate that glucose regulation is less efficient and warrants closer monitoring
- Elevated range: Sometimes highlights that further clinical assessment by an appropriate healthcare professional is advisable
If any result falls outside the expected range, this should be discussed with a qualified healthcare professional who can consider your full medical history. Our clinic provides testing and reporting only — we do not offer prescriptions or treatment services.

Frequently Asked Questions
1. What is the most important marker to include when keeping a record of diabetes screening results?
HbA1c is generally considered the most informative long-term biomarker for blood sugar levels, as it reflects average glucose over a 2–3 month period rather than a single moment. Including your HbA1c alongside fasting glucose in your record gives the most complete picture. Always note the unit of measurement (mmol/mol) and the laboratory's reference range.
2. How long should I keep my diabetes screening records?
There is no strict rule, but keeping records for a minimum of 3–5 years allows meaningful trend analysis. Digital records stored securely can be maintained indefinitely. The longer the record, the more informative it becomes when reviewing changes in blood glucose markers over time.
3. Can I track diabetes screening results at home alongside clinic tests?
Yes, many individuals use home glucose monitors between clinic appointments. However, home devices measure real-time blood glucose rather than HbA1c. Home readings are useful as a supplement to formal screening but should not replace laboratory-confirmed results when tracking long-term patterns.
4. What should I do if my diabetes screening results come back elevated?
An elevated result from a diabetes screen can suggest that further assessment by an appropriate healthcare professional is advisable. Our clinic provides testing and results reporting only. If your results indicate a concern, we recommend contacting your GP or an appropriate clinical service to discuss next steps in a full clinical context.
5. How does fasting affect diabetes blood test results?
Fasting — typically overnight for 8–12 hours — is required for accurate fasting glucose and fasting insulin measurements. Eating before a fasting test can temporarily elevate blood sugar readings and make results less reliable. HbA1c does not require fasting and can be measured at any time of day.
6. Is diabetes screening available without a GP referral in London?
Yes. Private walk-in clinics in London, including Walk In Clinic London, offer nurse-led diabetes screening without the need for a GP referral. This can be especially helpful for individuals who prefer not to wait for an NHS appointment or who wish to self-monitor their health proactively.
7. How is private diabetes screening different from NHS screening?
NHS diabetes screening is typically offered through GP practices and structured programmes such as the NHS Health Check. Private screening at a walk-in clinic offers greater flexibility in timing, no referral requirement, and faster results. Both provide accurate laboratory-tested results, though the clinical follow-up pathway may differ.
8. Can stress affect my HbA1c or blood glucose results?
Prolonged physical or psychological stress can sometimes influence blood glucose levels, as stress hormones such as cortisol can affect how the body regulates sugar. This is worth noting in your records alongside any result taken during a period of illness or significant stress.
9. Should I record units as well as numbers in my diabetes health log?
Yes, always. HbA1c is measured in mmol/mol in the UK (some older records may show percentage values). Glucose is measured in mmol/L. Recording units prevents confusion when comparing results from different laboratories or over extended periods.
10. What is the difference between a prediabetes result and a diabetes result on an HbA1c test?
An HbA1c of 42–47 mmol/mol may suggest a prediabetes range, sometimes called non-diabetic hyperglycaemia. A result of 48 mmol/mol or above can indicate diabetes. These are clinical reference ranges — they do not constitute a formal diagnosis without appropriate clinical assessment by a healthcare professional.
