There are both pros and cons to consuming coffee when fasting for a blood test. Coffee is a stimulant, and in some cases can act as a diuretic, which can potentially impact the results of a blood test.<\/p>\n

For most blood tests, the recommendation from medical professionals is to avoid consumption of all forms of caffeine, such as coffee, tea, energy drinks, and soda for 8 to 12 hours prior to the test. However, there are exceptions, so it is important to ask your doctor or the laboratory staff to clarify before the test.<\/p>\n

It is possible to drink coffee while fasting if given the all-clear by the doctor or laboratory testing staff. An occasional cappuccino or latte will not likely affect test results, as long as they are not consumed excessively. A cup of coffee may contain anywhere from 20-175 milligrams of caffeine, so if the amount of coffee consumed is kept to a minimum, results should still remain accurate. To be on the safe side, individuals should try to limit caffeine consumption to no more than two cups in a day, and try to complete any fasting tests as soon as possible after this initial two-cup limit. <\/p>\n

On the another hand, excess consumption of caffeine can lead to an increase in heart rate and an increase in blood pressure, which can interfere with test results. Certain tests require an individual to remain fasting for up to 16 hours or more, so it is important to take any required fasting time into consideration. It is also important to note that other sources of caffeine should not be consumed while fasting, such as chocolate and decaffeinated coffee, as these also contain varying levels of caffeine that can affect the results.<\/p>\n
