You may be wondering if it is okay to drink sparkling water before a fasting blood test. 

The answer is yes – you can drink sparkling water before a fasting blood test. However, it is important to note that you should not drink any other type of beverage before the test, including juice, milk, or soda.

Read on as I discuss this topic in more detail below.

Is it Okay to Drink Sparkling Water before a Fasting Blood Test?

Yes, it is okay to drink sparkling water before a fasting blood test. However, you want to be sure the sparkling water does not have any added sugars or sweeteners. If it does, you should avoid drinking it before the test.

In addition, you should not drink any other type of beverage before the test, including juice, milk, or soda. These beverages can affect your blood sugar levels and may give inaccurate results on the fasting blood test.

Will Sparkling Water Affect the Results of My Blood Test?

No. As I have mentioned above, as long as the carbonated water does not contain any hidden sugars or sweeteners, it will not affect the results of your blood test.

It is important to note that some sparkling water brands sneak in some artificial sweeteners and other additives that may not be good for you. So, if you are going to drink sparkling water before a fasting blood test, be sure to read the label carefully and choose a brand that is free of any unhealthy ingredients.

Can I drink Flavored Sparkling Water before a Fasting Blood Test?

While it is totally okay to drink unflavored sparkling water before a fasting blood test, you should take extra caution when drinking flavored sparkling water before going for your blood test.

Why is this the case? Most flavored sparkling water brands introduce hidden sugars and sweeteners in their drinks. As I have mentioned before, these added sugars can skew the results of your fasting blood test.

How to Safely Drink Sparkling Water before a Fasting Blood Test

If you have to drink sparkling water before a fasting blood test, be sure to choose a brand that is sugar-free and additive-free. You can also drink plain sparkling water, without any added flavors.

You want to choose trusted brands of sparkling water that are known for their quality and lack of unhealthy ingredients. Some good examples include LaCroix, Perrier, and Topo Chico.

How Often Should I Drink Sparkling Water Before a Fasting Blood Test?

How often you drink sparkling water before a fasting blood test will depend on the specific brand of sparkling water you choose. You can drink as often as you want as long the water has no additives and is sugar-free.

Just be sure to avoid drinking any other type of beverage before the blood test, including juice, milk, and soda. These beverages can affect your blood sugar levels and may give inaccurate results on the fasting blood test.
