Whats My Target Range
You might be asking, what’s the normal range for blood sugar levels? The answer is, there is a healthy range that you should ideally be aiming for. The infographics above show the general guidelines, but your individual target range for your blood sugar levels may be different. Youll healthcare team will agree with you what it is.
Youll get different readings at different times of the day, depending on things like what youve eaten and how much you are moving around. Heres a guide to help you get started on finding your target range:
If youre a child with Type 1 diabetes
- when you wake up and before meals: 4 to 7mmol/l
- after meals: 5 to 9mmol/l
If youre an adult with Type 1 diabetes
- when you wake up and before meals: 5 to 7mmol/l
- before meals at other times of the day: 4 to 7mmol/l
If you have Type 2 diabetes
- before meals: 4 to 7mmol/l
- two hours after meals: less than 8.5mmol/l
Oral Glucose Tolerance Test
This test is not now usually used to diagnose diabetes. However, the test may be done if it is thought your body doesn’t control glucose levels normally but not badly enough to be called diabetes. This is referred to as pre-diabetes . The test may also be used to see whether a woman has developed diabetes associated with pregnancy.
For this test, you fast overnight. In the morning you are given a drink which contains 75 g of glucose. A blood sample is taken two hours later. Normally, your body should be able to deal with the glucose and your blood level should not go too high. A glucose level of 11.1 mmol/L or more in the blood sample taken after two hours indicates that you have diabetes. See the separate leaflet called Glucose Tolerance Test for more details.
What Causes Low Blood Sugar
Low blood sugar has many causes, including missing a meal, taking too much insulin, taking other diabetes medicines, exercising more than normal, and drinking alcohol. Blood sugar below 70 mg/dL is considered low.
Signs of low blood sugar are different for everyone. Common symptoms include:
Know what your individual symptoms are so you can catch low blood sugar early and treat it. If you think you may have low blood sugar, check it even if you dont have symptoms. Low blood sugar can be dangerous and should be treated as soon as possible.

How Do I Prepare For The Plasma Glucose Level Test And How Are The Results Interpreted
To get an accurate plasma glucose level, you must have fasted for at least 8 hours prior to the test.

According to the practice recommendations of the American Diabetes Association, the results of the blood test are interpreted as follows:
Fasting blood glucose level
- If your blood glucose level is 70 to 99* mg/dL . . .
- What it means: Your glucose level is within the normal range
*Values between 50 and 70 are often seen in healthy people
**The condition of “prediabetes” puts you at risk for developing Type 2 diabetes, high blood pressure, and blood lipid disorders

Common Problems To Avoid
It’s important to regularly maintain your glucose meter to avoid potential problems. Follow these tips to ensure good functioning:
- Make sure you keep batteries in stock that fit your glucometer.
- Make sure your test strips are not expired, as expired test strips can provide an inaccurate result.
- After taking a test strip out, close the lid tightly. Too much light or moisture can damage the strip.
- Clean your device at regular intervals and run quality-control checks when prompted.
- Wash hands well before testing since food residues can affect the number.
- Let the alcohol dry since it can cause false lows.

How It Is Done
involves pricking your finger, palm, or forearm with a lancet to collect a drop of blood. The blood drop is placed on a test strip, which you insert into the blood glucose meter. The instructions for testing are slightly different for each blood glucose meter model. Follow the instructions that came with your meter.
- Wash your hands with warm, soapy water. Dry them well with a clean towel. You may also use an alcohol wipe to clean your finger or other site. But make sure your hands are dry before the test.
- Insert a clean lancet into the lancet device.
- Remove a test strip from the test strip bottle. Replace the lid right away to keep moisture away from the other strips.
- Follow the instructions that came with your meter to get it ready.
- Use the lancet device to stick the side of your fingertip with the lancet. Do not stick the tip of your finger. Some blood sugar meters use lancet devices that take the blood sample from other sites, such as the palm of the hand or the forearm. But the finger is usually the most accurate place to test blood sugar.
- Put a drop of blood on the correct spot on the test strip.
- Apply pressure with a clean cotton ball to stop the bleeding.
- Follow the directions that came with the meter to get the results.
- Write down the results and the time that you tested your blood. Some meters will store the results for you.

How To Do A Finger
Your healthcare team will show you how to do it the first time, but these are the key steps:

- Take a test strip and slot it into the meter to turn it on. Some meters will have tests strips built in.
- Remove the cap from your finger prick device and put in a new lancet. Then put the cap back on and set the device by pulling or clicking the plunger.
- Choose which finger to prick but avoid your thumb or index finger . And dont prick the middle, or too close to a nail. Place the device against the side of your finger and press the plunger. Use a different finger each time and a different area.
- Take your meter with the test strip and hold it against the drop of blood. Itll tell you if the test strip is filled, usually by beeping.
- Before you look at your reading, check your finger. Use a tissue to stop bleeding, then use it to take out the lancet and throw it away in your sharps bin.
- You can use the same tissue to take out the test strip and throw that away too. Taking out the strip will usually turn the meter off.
