Tests for Blood Sugar and HbA1c
In this article
If your glucose level remains high then you have diabetes. If the level goes too low then it is called hypoglycaemia.
The main tests for measuring the amount of glucose in the blood are:
- Random blood glucose level.
- Capillary blood glucose .
- Urine test for blood sugar .
What Can Affect My Results
If you consistently see results that arenât expected, recalibrate your meter and check the strips.
The chart below shows you the ideal blood sugar ranges for most adults except for pregnant women. Your ideal range may be different from another person’s and will change throughout the day, so check with your doctor for your targets.
Time of Test
If You’re Diagnosed With Diabetes
What the GP will discuss with you during your appointment depends on the diagnosis and the treatment they recommend.
Generally, they’ll talk to you about:
- what diabetes is
- what high blood sugar means for your health
- whether you need to take medicine
- your diet and exercise
- your lifestyle for example, alcohol and smoking

Who Should Have A Diabetes Test
You should have a diabetes test if you are at a high risk of type 2 diabetes. An AUSDRISK score of 12 or more is considered high risk.
You may also be at high risk of diabetes if you:
- have had a heart attack or stroke
- have had gestational diabetes
- take medications to treat psychosis
You should have a diabetes test every year if you have pre-diabetes.
Tips To Make Glucose Monitoring Easier
Whether youre using a traditional finger prick monitor or a CGM for your diabetes management, here are some tips to make checking your glucose easier:
- Always wash your hands with soap and water before checking your glucose for a more accurate result. Dont use hand sanitizer before using finger sticks.
- If inserting a sensor into your skin for a CGM, be sure to wash the area of skin with soap and water and allow it to dry first.
- Change any sensors by the recommended manufacturer time for example, every 14 days for the FreeStyle Libre and every 10 days for the Dexcom G6.
- If using finger strips, you may experience less pain by using the side of your fingertip closer to your fingernail.
- Even if youre using a CGM, you may consider having a traditional meter on hand to double-check your glucose. This is in case you experience symptoms of high or low blood sugar despite a normal reading.

Which Tests Help My Health Care Professional Know What Kind Of Diabetes I Have
Even though the tests described here can confirm that you have diabetes, they cant identify what type you have. Sometimes health care professionals are unsure if diabetes is type 1 or type 2. A rare type of diabetes that can occur in babies, called monogenic diabetes, can also be mistaken for type 1 diabetes. Treatment depends on the type of diabetes, so knowing which type you have is important.
To find out if your diabetes is type 1, your health care professional may look for certain autoantibodies. Autoantibodies are antibodies that mistakenly attack your healthy tissues and cells. The presence of one or more of several types of autoantibodies specific to diabetes is common in type 1 diabetes, but not in type 2 or monogenic diabetes. A health care professional will have to draw your blood for this test.
If you had diabetes while you were pregnant, you should get tested no later than 12 weeks after your baby is born to see if you have type 2 diabetes.
What Happens During A Diabetes Test
Diabetes is usually tested by using a blood glucose test. Normally, a blood sample is taken from your vein and sent to a pathology lab for analysis.
There are different types of blood tests. You may be asked to fast overnight beforehand or you may not need to prepare. You may be asked to take an oral glucose tolerance test. For this test, you are asked to fast, have a blood sample taken, then drink a sugary drink provided for you and have another blood sample taken 2 hours later.

How Does A Flash Glucose Monitor Work
A flash glucose monitor has two parts:
- A sensor that you wear just under your skin which measures your sugar levels.
- A reader that you or someone else can swipe over the sensor to get both your sugar level and the trend of your levels. You can also scan the sensor with your phone.
Each time you scan your sensor, you can access the last eight hours of sugar levels. Flash glucose monitoring also comes with software so you can analyse your results and see patterns in your sugar levels.
You generally wear a sensor for about 14 days, after that you need to put on a new one.
Sensors should be worn on the arms only, and we recommend that they aren’t placed over areas with tattoos as this could impact your results.
How Often Should I Test My Blood Sugar Level
Your family doctor will recommend how often you should test. Testing times are based on the kind of medicine you take and on how well your blood sugar levels are controlled. Youll probably need to check your blood sugar more often at first. Youll also check it more often when you feel sick or stressed, when you change your medicine, or if youre pregnant.

Driving And Checking Your Blood Sugars
You can use a flash glucose monitor to check your sugar levels when driving, but you must confirm your levels with a finger-prick test if:
- your blood sugar level is 4 mmol/l or below
- you have symptoms of a hypo
- your monitor gives a reading thats not consistent with the symptoms youre getting for example, if you feel like youre having a hypo but the reading doesnt show this.
Together, our campaigning changed the law on driving and checking your sugar levels. Weve campaigned for years to make sure the law is fair. So that you can carry on driving and take the right steps to stay safe at the wheel.

Fda Approves First Blood Sugar Monitor Without Finger Pricks
Associated PressSept. 28, 2017
U.S. regulators have approved the first continuous blood sugar monitor for diabetics that doesnt need backup finger prick tests.
Current models require users to test a drop of blood twice daily to calibrate, or adjust, the monitor.
The pain of finger sticks and the cost of testing supplies discourage many people from keeping close tabs on their blood sugar, which is needed to manage insulin use and adjust what they eat.
Abbotts new FreeStyle Libre Flash Glucose Monitoring System, approved Wednesday by the Food and Drug Administration, uses a small sensor attached to the upper arm. Patients wave a reader device over it to see the current blood sugar level and changes over the past eight hours.
Most of the 30 million Americans with diabetes use standard glucose meters, which require multiple finger pricks each day and only show current sugar level. More-accurate continuous glucose monitoring devices are used by about 345,000 Americans.
But most dont do the finger pricks to calibrate them and may get inaccurate readings, said Dr. Timothy Bailey, who helped test FreeStyle Libre.
Were able to lower blood sugar safely with this technology, said Bailey, director of the Advanced Metabolic Care and Research Institute in California. He receives consulting fees from various diabetes device makers.

What If I Cant Get A Drop Of Blood For A Fingerstick
If you want to get blood from your fingertip, try washing your hands in hot water to get the blood flowing. Then dangle your hand below your heart for a minute. Prick your finger quickly and then put your hand back down below your heart. You might also try slowly squeezing the finger from the base to the tip.
The Guardian Connect System
The Guardian Connect System is a CGM device that can send early warnings of potential high glucose levels to a person before they occur. The company reportedly works with over 600 insurance companies to help people get the system at a lower price.
The Guardian Connect System features:
- a rechargeable transmitter that does not need replacing
- a smartphone app for Android and iOS devices
- a free 30-day trial
FDA approval in 2018.
It measures the glucose in the interstitial fluids every 5 minutes before sending information to the linked app. The sensors work for up to 90 days, so a person needs to replace them every 3 months.
However, the device requires individuals to visit their doctors office for insertion, so it may not be the best option for those unable to leave their house or see their doctor in person.
Additionally, the Eversense CGM can be sensitive to direct sunlight. This may affect the insertion site, often in the upper arm.

Other Tips For Checking:
- With some meters, you can also use your forearm, thigh, or fleshy part of your hand.
- There are spring-loaded lancing devices that make sticking yourself less painful.
- If you use your fingertip, stick the side of your fingertip by your fingernail to avoid having sore spots on the frequently used part of your finger.
How Do I Pick A Glucose Meter
Your doctor will make a recommendation. Check with your health insurance plan to see if it will pay for your BGM, its supplies, or a CGM. If so, your plan may only pay for a certain meter.
Shop around and compare costs. Consider what features are important to you. For example, some meters are made for people who have poor eyesight. If you want to pay a little more money, you can get a BGM that stores the results in its memory. This allows you to compare results from several days at one time.

How To Use A Blood Glucose Meter:
- After washing your hands, insert a test strip into your meter.
- Use your lancing device on the side of your fingertip to get a drop of blood.
- Touch and hold the edge of the test strip to the drop of blood and wait for the result.
- Your blood glucose level will appear on the meter’s display.
Note: All meters are slightly different, so always refer to your user’s manual for specific instructions.
What Do My Results Mean
When you finish the blood sugar check, write down your results and note what factors may have affected them, such as food, activity, and stress. Take a close look at your blood glucose record to see if your level is too high or too low several days in a row at about the same time. If the same thing keeps happening, it might be time to change your diabetes care plan. Work with your doctor or diabetes educator to learn what your results mean for you. It can take time to make adjustments and get things just right. And do ask your doctor if you should report results out of a certain range right away by phone.
Keep in mind that blood glucose results often trigger strong feelings. Blood sugar numbers can leave you upset, confused, frustrated, angry, or down. It’s easy to use the numbers to judge yourself. Remind yourself that tracking your blood sugar level is simply a way to know how well your diabetes care plan is working, and whether that plan may need to change.

Who Are They Useful For
CGMs can help people with diabetes monitor and maintain their blood glucose levels. While they do not involve finger pricking, they may be useful to calibrate the device.
Earlobe, breath, and other noninvasive devices may be beneficial for monitoring blood glucose levels, especially in children with the same condition and those who have cystic fibrosis. However, they are not FDA-approved, while some may need to undergo further testing to determine their safety and accuracy.
