Stay Hydrated: Drink water prior to testing to facilitate easier sample collection.

Time of Day: Schedule blood tests in the morning, preferably between 7:00-10:00 AM.

Medications and Supplements: Ideally, blood samples should be taken before your morning dose. Certain medications can interfere with test results, so consult your doctor about delaying your dose due to lab tests.

Other Factors: Avoid performing tests after a sleepless night or intense physical activity. Before blood collection, it's best to avoid exercise, stress, and smoking. A short rest prior to the test is recommended.

Fasting: Fast for approximately 12 hours before blood sampling. Your last meal should ideally be around 6:00 PM the previous day. Avoid heavy, fatty meals and alcohol before the test.

Biotin Supplements: High doses of biotin can affect test results. It’s advised to avoid taking biotin for at least 72 hours prior to blood collection. Inform the lab personnel if you're taking biotin so they can provide specific instructions.

Diet and Hydration: Maintain a normal diet and drink plenty of fluids to ensure a normal urine volume.

Abstain from Sexual Activity: Avoid sexual activity before providing a urine sample.

Clean the Urethral Area: Wash the area around the urethra with warm water, without using any cleaning or disinfecting products.

Sample Collection: For routine urinalysis, a midstream urine sample should be collected in a clean, disposable container from a pharmacy or provided by the laboratory.

Label the Container: Label the container with your name, date of birth, and the date and time of collection.

Menstrual Period Considerations: Women should avoid providing a urine sample during their menstrual period or within two days of its completion, as this can affect the test results.
