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: Plan your blood draw for the morning following an overnight fast, unless otherwise directed by your healthcare provider.
Avoid collection: N/A.
Fasting: Recommended. Do not eat or drink for at least 8 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: Continue taking prescribed medications unless otherwise directed by your health care provider.
- 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, refrain from consuming alcohol, excessive caffeine, and heavily processed foods
- Supplements: For 72 hours before collection, avoid 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), 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.
