Starting your journey to better health? It's all about getting to know the unique language of your body's biomarkers. At Keyspan, our mission is to give you clear, personalized insights and strategies that go beyond the usual one-size-fits-all advice and random supplement picks.

Your blood test is where it all begins. It's our way of peeking into what's happening inside you, setting the stage for the tailored plan and specific supplements we'll create just for you. Getting ready for your blood test is crucial—it's all about ensuring we get the clearest picture possible from the get-go.

Here are some tips to prep for your test and make sure we're getting the most accurate results:

The Importance of Fasting

    Fasting for at least 12 hours prior to your blood draw is essential. This period of fasting ensures that your bloodstream is clear of sugars, fats, proteins, and other nutrients that could otherwise skew the results of your blood test. By doing so, you're allowing us to capture a true baseline of your biomarkers, paving the way for personalized health recommendations.

    Stay Hydrated

    While you're fasting, remember to stay hydrated. Drinking plenty of water not only keeps you comfortable but also has practical benefits for the blood draw itself. Increased hydration leads to a higher blood volume, making your veins more accessible and potentially speeding up the process.

    Avoid Alcohol Intake

    It's advisable to avoid alcohol for at least 24 hours before your test. Alcohol can temporarily spike certain markers in your blood, such as glucose, triglycerides, and the liver enzyme GGT. To ensure the integrity of your results, we recommend abstaining from alcohol to capture your body's true state.

    Supplement Consideration

    Just like with alcohol, supplements can temporarily alter the levels of certain biomarkers. To avoid these potential distortions, please refrain from taking any supplements for 48 hours before your blood draw. This includes common vitamins and minerals, as well as any IV infusions you may be receiving.

    Medication Protocol

    If you're on any prescribed medications, continue taking them as usual unless otherwise directed by your healthcare provider. It's important that your test results reflect your body's state under your current medication regimen

    Exercise and Rest

    In the days leading up to your test, try to avoid any strenuous exercise. Intense physical activity can elevate certain biomarkers related to muscle breakdown and inflammation, such as liver enzymes and creatine kinase. A gentle approach to your activities in the 48 hours before your test can help ensure that your results reflect your body's typical state.

    Dress for Success

    Choosing the right attire for your blood draw can make a significant difference. We recommend wearing loose, comfortable clothing with sleeves that can be easily rolled up or fastened back. This not only facilitates access for the phlebotomist but also ensures your comfort throughout the procedure. Consider layers, so you can adjust based on the room's temperature, ensuring you remain relaxed and stress-free.

    Mental Prep - Finding Your Calm 

    Feeling anxious about needles is entirely normal, but there are strategies to help manage these feelings. Practice deep breathing exercises or mindful meditation in the moments leading up to your appointment. Visualize a calm and serene place, or bring along a book or music that soothes you. Remember, this test is a proactive step towards understanding and enhancing your well-being. Focusing on the positive impact this test will have on your health journey can transform anxiety into anticipation for the benefits to come.

    Nourish and Nurture

    Post-blood draw care is just as important as the prep. Once the draw is complete, it's common practice to apply firm pressure to the site with a clean bandage or gauze to prevent bruising. Keep the bandage on for at least a few hours. Also, rehydration is key after fasting; ensure you drink plenty of water to replenish your fluids. If you feel light-headed, take a moment to sit and rest until you feel steady. Remember, your body has just contributed to your future health insights, so treat it with care.


    By following these preparation steps, you're setting the stage for the most accurate and insightful blood test results. This will empower both you and your Keyspan health team to tailor a health strategy that resonates with your body's specific needs and goals.
