Avoid taking a blood age test if you have recently taken antibiotics (within 2 weeks), received immunizations or vaccines, or are currently experiencing an infection. Postpone the test if you've had recent surgery or trauma, consumed alcohol, or are not fasting. Pregnancy, breastfeeding, recent use of alcohol or recreational drugs (within 48 hours), and being on medications that may interfere with results are also factors to consider. Additionally, avoid testing if you've had a recent blood transfusion, are menstruating, or undergoing chemotherapy.     If any of these conditions apply, please contact our customer care team for further guidance.
