I want to take a blood test to know which is my blood type. can this test detect pregnancy??

Separately: You will have to ask the blood lab to run both tests to know both the blood type and pregnancy result if it is from the same sample.

No: Test for blood group and pregnancy are very different tests. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Get HPV vaccine.
