# Check whether diabetes testing is due Published by Pawel Jozefiak. [About this project](https://healthy100.jock.pl/about/), [How we check sources](https://healthy100.jock.pl/methodology/) - Canonical: https://healthy100.jock.pl/screen-diabetes-risk/ - Language: en - First published: 2026-09-27 - Evidence checked: 2026-09-28, using AI-assisted source verification - Clinical review: Not clinically reviewed - Number 42 of 100 in the list: https://healthy100.jock.pl/#screen-diabetes-risk Testing can uncover diabetes or prediabetes early enough to arrange care and prevent complications. **The number:** Screen ages 35 to 70 with overweight or obesity ([USPSTF, 2021](https://www.uspreventiveservicestaskforce.org/uspstf/recommendation/screening-for-prediabetes-and-type-2-diabetes)) ## The evidence - Evidence grade: A. Grade A: meta-analyses of randomised trials, or a major guideline consensus. - Basis: USPSTF recommendation based on screening trials and evidence for preventive interventions - Impact: 65/100. The impact score is an editorial prioritization heuristic for the general list, not a validated estimate of your personal risk. ## Why it matters Blood glucose can be high before symptoms appear. The 2021 USPSTF recommendation covers adults aged 35 to 70 with overweight or obesity, followed by effective prevention when prediabetes is found. Screening itself has not clearly reduced mortality in trials, so its value depends on the care that follows. ## How to do it 1. Ask about HbA1c or fasting blood glucose if you meet the screening criteria. 2. Tell your clinician about diabetes in close relatives or diabetes during a past pregnancy. 3. Ask whether an abnormal result needs a repeat test before a diagnosis. 4. If results are normal, discuss when to repeat testing; about 3 years is reasonable for the USPSTF group. ## Talk to a clinician first Symptoms, pregnancy and higher inherited risk need a separate testing plan. HbA1c can be misleading with some blood conditions. ## Putting it into practice ### Start now - 1 minute: Recall whether a parent or sibling has diabetes, or you had diabetes in pregnancy; bring this up when asking about testing. - 5 minutes: Ask your clinic whether your age and risk factors mean a diabetes blood test is due. - 15 minutes: Gather previous results and family or pregnancy history; prepare questions about the test, confirmation of abnormal results and repeat testing. ### What it looks like - Tell your clinician if you had diabetes during pregnancy, even if your glucose later returned to normal. - Ask which blood test is planned and what preparation it needs. ### Common mistakes - A home glucose meter cannot diagnose diabetes, so arrange clinical testing if you are concerned. - Different blood tests need different preparation, so ask the service instead of starting a fast yourself. ### A structured start **Turn a test into a care plan** 1. Ask whether testing is appropriate, including any symptoms or pregnancy. 2. Book the agreed test and get preparation instructions from the service. 3. Discuss the result and whether confirmation is needed. 4. If prediabetes is found, ask about a prevention programme; otherwise agree when to review testing. ### Trusted how-to guides - [Diabetes Tests and Diagnosis](https://www.niddk.nih.gov/health-information/diabetes/overview/tests-diagnosis), NIH NIDDK ## In Czechia In Czechia, blood glucose is tested at every preventive check with your GP, which adults from 18 have every 2 years. [Národní zdravotnický informační portál (NZIP)](https://www.nzip.cz/clanek/441-vseobecne-preventivni-prohlidky-dospelych), checked 2026-09-28 ## In Germany In Germany, statutory insurance covers a Gesundheits-Check-up once between 18 and 34 and every 3 years from 35. It includes a blood sugar test, which at 18 to 34 is only done if you have risk factors; arrive fasting. [Bundesministerium für Gesundheit, gesund.bund.de](https://gesund.bund.de/gesundheits-check-up-fuer-erwachsene), checked 2026-09-28 ## In Netherlands In the Netherlands, your risk of type 2 diabetes is higher if you are over 45 with a risk factor such as overweight, diabetes in the family or high blood pressure, or from 35 with a Hindustani background. Your GP can then check your blood sugar once every 3 years. [Nederlands Huisartsen Genootschap, Thuisarts](https://www.thuisarts.nl/diabetes-type-2/ik-heb-grotere-kans-op-diabetes-type-2), checked 2026-09-28 ## In Poland In Poland, the free Moje Zdrowie programme for adults from 20 includes a blood glucose test. It is available every 5 years at 20 to 49 and every 3 years from 50; start with the questionnaire in IKP, mojeIKP or at your POZ.
