A member asked:
Will getting a cbc require fasting?
A doctor has provided 1 answer
Complete blood count: CBC = complete blood count. The test looks at your red cells, white cells and platelets only. It does not require for you to fast before the test. If, however, other tests are being done at the same time, you may need to fast for those.
