Important:
For optimal and clinically relevant results, patients should maintain their routine diet, medications, and supplements unless specifically instructed otherwise by their healthcare provider.
Time of Collection: Schedule your blood draw in the morning after an overnight fast. Collect the first-morning urine sample upon waking.
Avoid collection: N/A
Fasting: Recommended. Do not eat or drink for at least 9-12 hours before blood collection.
Consult your healthcare provider before making any lifestyle changes, including changes to prescribed medications, dietary restrictions, or supplements.
RECOMMENDED: Preparing for the Test to Avoid Test Interference
- Medications: Do not discontinue any prescribed medication without your healthcare provider's instruction. Avoid antibiotics or corticosteroids for 72 hours before collection.
- Hydration: Ensure adequate hydration by drinking 8 glasses of water per day for 2-3 days before the test. On the collection day, do not drink more than 8 oz of water 1 hour prior to urine collection.
OPTIONAL: Preparing for the Test to Avoid Biological Effects
- Diet: For 48 hours before collection, avoid antioxidants (e.g., berries, leafy greens, nuts, cocoa, seeds). For 24 hours before collection, avoid antioxidants (e.g., berries, leafy greens, nuts, seeds), refrain from consuming alcohol, excessive caffeine, and heavily processed foods
- Supplements: For 72 hours before collection, avoid antioxidant supplements like (e.g., vitamin C, vitamin E, CoQ10), high-dose antioxidant or anti-inflammatory supplements (e.g., vitamin A, beta-carotene, vitamin C, vitamin E, alpha-lipoic acid, selenium, zinc, fish oil, CoQ10, curcumin, resveratrol, ginger, quercetin, Boswellia), and biotin supplements
- Environmental Factors: Avoid intense physical exercise and exposure to environmental pollutants (e.g., cigarette smoke, exhaust fumes) 24 hours before the test.
Test Interference: Test interference occurs when a food, supplement, or medication alters the sample or directly interferes with testing reagents. Test interference causes an inaccurate result (e.g., false positive, false negative, false higher, or false lower).
Biological Effects: Even without interfering with the test, some substances can influence your body's biomarkers, affecting your results by increasing or decreasing the biomarker. However, biological effects do not interfere with test performance, accuracy, or validity. Results will be accurate as measured.
