How to test your blood glucose (sugar) levels

It’s usually difficult to take in everything the GP tells you during the appointment.

Talk to family and friends about what the GP told you, and write down any questions you have.

Then make another GP appointment and take your list of questions with you.

There’s also a lot of information on diabetes available.

Instructions For Checking Your Blood Sugar

Your healthcare provider will tell you how often to check your blood sugar. Theyll also tell you what your blood sugar level should be. This is called your blood sugar target range. Your blood sugar target range is based on your overall health and current treatment plan.

When youre ready to start, wash your hands with soap and water. Dry them very well. Touching a blood glucose test strip with damp hands can damage it or make your result less accurate.

Get Your Lancing Device Ready

  • Twist the white band on your lancing device to the right to unlock the endcap .

    When To Measure Blood Glucose

    • Blood glucose should be measured whenever your patient with diabetes is feeling unwell in any way.
    • In the diabetic patient, it should be measured before surgery to ensure that the patient is not going be become unwell during surgery and/or after general anaesthetic. Measure regularly until the patient is eating and drinking normally and blood glucose is stable.
    • In newly diagnosed diabetes patients, more frequent measurements are needed, until blood glucose is stable.

    Choosing A Blood Glucose Monitor

    English Guide Sinocare GA

    A blood glucose monitor, testing strips, and a lancet to draw the blood are all necessary for testing. Some testing kits offer all three, while others require separate purchases for each piece.

    People with diabetes use many testing strips, and so it may be wise to carefully consider the cost of the testing strips as well as the monitor.

    Some other tips for buying a monitor include:

    • Select one with automatic coding to avoid the need to code in results with every test.
    • Check insurance plans to see if an insurer only covers certain monitors.
    • Look at whether the unit stores previous data.
    • Consider portability, since larger units can be difficult to carry around.
    • Think about blood sample size, particularly for people who do not like pricking themselves.

    Monitors that require a smaller blood sample may be more comfortable as the depth of the lancet can be less.

    Many people with diabetes have no signs of the disease at all. However, the lack of symptoms does not necessarily mean the absence of diabetes.

    When symptoms occur, many of the effects of type 1 and type 2 diabetes are the same since both affect blood sugar regulation in the body. Symptoms include:

    • increased hunger and thirst

    What Blood Sugar Levels Are Healthy

    This is the big question.

    Weve established what normal non-diabetic blood sugar looks like, more or less. And we know what blood sugar goals the medical authorities set for people with diabetes. The problem is that theres some distance between those two levels. Many in the Diabetes Daily community have reasoned that it is best to get their blood sugar as close to normal as is reasonably possible. Should your target be normal blood sugar, the ADA target, or something in between?

    The truth is that this is something of a gray area both in the diabetes recommendations and in the medical research. Speaking very generally, the long-term studies that the ADA uses to set its glycemic targets tend to show that the risk of long-term complications such as kidney disease and retinopathy drops off significantly when a patients A1C is lower than 6.5-7 percent. There are plenty of individual studies suggesting that even lower blood sugar levels are as associated with even better health, but the diabetes establishment has not yet made it a priority to issue guidance on the matter.

    That leaves us with a situation in which some doctors and endocrinologists tell their patients that an A1C of 7 percent is good enough, while others encourage their patients to try and get as close to normal as possible provided that it doesnt involve an undue risk of hypoglycemia. Some, like the popular Dr. Richard Bernstein, have made the latter approach the guiding philosophy of their practices.

    What Is Being Tested

    This test measures the amount of glucose in your blood. Glucose is a simple sugar that provides energy for the body.

    People with diabetes often monitor their own blood glucose at home. This is done using a finger-prick test and a special machine, rather than a blood sample taken from a vein.

    You might have blood taken for a blood sugar level. You might or might not be asked to fast beforehand.

    There is also a test called an oral glucose tolerance test, abbreviated as OGTT or GTT. For this test you fast, then have a blood sample taken, then drink glucose, then have a number of samples taken over a few hours.

    What Abnormal Results Mean

    If you had a fasting blood glucose test:

    • A level of 100 to 125 mg/dL means you have impaired fasting glucose, a type of prediabetes. This increases your risk of developing type 2 diabetes and you should consult with your provider.
    • A level of 126 mg/dL or higher usually means you have diabetes.

    If you had a random blood glucose test:

    • A level of 200 mg/dL or higher often means you have diabetes.
    • Your provider will order a fasting blood glucose, A1C test, or glucose tolerance test, depending on your random blood glucose test result.
    • In someone who has diabetes, an abnormal result on the random blood glucose test may mean that the diabetes is not well controlled. Talk with your provider about your blood glucose goals if you have diabetes.

    Other medical problems can also cause a higher-than-normal blood glucose level, including:

    • Weight loss after weight loss surgery
    • Vigorous exercise

    Some medicines can raise or lower your blood glucose level. Before having the test, tell your provider about all the medicines you are taking.

    For some thin young women, a fasting blood sugar level below 70 mg/dL may be normal.

    Normal Blood Sugar Ranges

    How to check your blood sugar

    Its recommended that fasting blood sugar levels be between 80 mg/dL to 130 mg/dL as often as possible for people with diabetes. Postprandial blood sugar, which is taken two hours after a meal, should be less than 180 mg/dL. Understanding these levels can be important when interpreting your own readings. However, its very important to note that you shouldnt compare your levels to others and every single person has a different diabetes journey.

    Testing Times For Type 2 Diabetes

    People with type 2 diabetes taking supplementary insulin often test several times day, including:

    • Before all meals
    • Before going to bed.

    You may be able to test less frequently if you are only taking intermediate- or long-acting forms of insulin. Individuals managing their diabetes with oral medications and lifestyle changes rather than insulin are not required to test daily.

    How Can I Treat High Blood Sugar

    Talk to your doctor about how to keep your blood sugar levels within your target range. Your doctor may suggest the following:

    • Be more active. Regular exercise can help keep your blood sugar levels on track. Important: dont exercise if ketones are present in your urine. This can make your blood sugar go even higher.
    • Take medicine as instructed. If your blood sugar is often high, your doctor may change how much medicine you take or when you take it.
    • Follow your diabetes meal plan. Ask your doctor or dietitian for help if youre having trouble sticking to it.
    • Check your blood sugar as directed by your doctor. Check more often if youre sick or if youre concerned about high or low blood sugar.
    • Talk to your doctor about adjusting how much insulin you take and what types of insulin to use.

    Defining Normal Blood Sugar

    Manydifferentstudies have been performed to measure the blood sugar of people without diabetes, particularly since the advent of continuous glucose monitoring technology.

    You will find normal blood sugar that is, the blood sugar levels that metabolically healthy tend to exhibit defined differently in different places. The United States and Europe, notably, have different standards for pre-diabetes. But most American authorities show something like the following:

    • Fasting blood sugar: 70-100 mg/dL
    • Post-prandial blood sugar : 100-140 mg/dL
    • A1C: < 5.7 percent

    Studies show that many people without diabetes do experience blood sugar levels above 140 mg/dL after meals, but such peaks are usually fairly brief. A 2010 analysis showed that 93 percent of healthy study participants reached or exceeded 140 mg/dL, but they spent a median of just 26 minutes per day at that level.

    Most people without diabetes will likely be very close to 100 percent time-in-range.
