How And When To Get Your Blood Test for Diabetes

12,Mar,2021

Diabetic patients need regular blood sugar tests to check the level of glucose in their blood. The blood sugar test result helps the doctor understand your condition and manage it to avoid complications arising from diabetes.

Different diabetes testing are available, and you can check your blood sugar level with the following methods.

  • Fingerprick

Fingerprick blood sample collection involves collecting blood from your fingertip. You would prick the tip of your finger with a small, sharp needle (lancet), then put a drop of your blood on the blood sugar test strip and put the test strip in a glucometer which will show the level of your blood sugar.  

The result will be available within 15 seconds, and the glucometer will store your result if your doctor needs to analyse your glucose level over a period. Some glucometres can tell you your average blood sugar level over a certain period, show graphs and charts of your results.  

Different blood sugar metres are available with testing strips, and you can get one at your local pharmacy.  

  • Metres for testing blood collected from other sites

The new types of blood sugar meters allow you to check your blood sugar level with blood sample gotten from sites other than the fingertip. These sites include the thigh, forearm, upper arm, and base of the thumb.

Blood gotten from these sites may give a different result from samples gotten from the fingertip. The blood sugar levels from fingertips show rapid changes than blood samples gotten from other sites, especially when your blood sugar level changes rapidly, like after exercising or eating.

If you experience hypoglycaemia symptoms and want to check your blood sugar level, it is best to use a fingertip blood sample because it gives a more accurate reading/

  • The continuous glucose monitoring system

The devices used for this test are also known as interstitial glucose monitoring devices. They are usually combined with insulin pumps. This device works like the finger-prick glucose metre, and it shows your blood sugar pattern over a certain period.

When you should test your blood sugar

Persons with diabetes have to check their blood sugar level multiple times a day, including after an exercise, before going to bed, and after meals. Testing your blood sugar level is also necessary when you show symptoms of low blood sugar.

People differ and respond differently to the condition, so you should ask your doctor when and how often you need your blood test for diabetes. When sick, you have to check your blood sugar level more often.  

What affects your blood sugar test result?

Certain conditions like gout and anaemia affect blood sugar level. Your environment, such as being at a high altitude or a hot place, can affect the level of glucose in your blood. If you notice an unusual blood sugar test result, recalibrate the test metre and check your strip before re-testing your blood sugar.  

People have different blood sugar ranges at different times of the day and in different environments. The table below should give you an idea of the ideal blood sugar level and normal range at different times.

Normal ranges for diabetic adults

Before meals

70 – 130 mg/dL

After meals

Below 180mg/dL

 

Home blood glucose monitoring and HbA1c

To control your diabetic condition, you need to monitor your HbA1c level constantly. Most home blood sugar metres show the average blood sugar level over time, which is the same as HbA1c.

When should I contact my doctor concerning my blood sugar level?

When you visit your doctor, ask for the target range of your blood sugar, then ask for ways to manage low and high blood sugar level results. Ensure you also ask when to contact your doctor. Your doctor will tell you signs of high and blood sugar levels to look out for and how you should manage the symptoms.  

How do I record my test readings?

It is important to keep a record of all urine, ketone, and blood test. Most glucometres automatically save your test readings and notify you when you have abnormal results or pattern. Your doctor can use this record to know when you need to change your eating plan, exercise program or medication. Whenever you visit our doctor, make sure you have a record of your test result with you.
