My Nightingale: why we use blood to measure health

There are many ways to keep a tab on your health, but we trust blood. Here’s why.

Your blood holds the truth about your health. It not only gives comprehensive but the most current and scientifically backed information. This makes blood tests one of the best ways to track and improve your wellbeing. Here’s why we believe in blood:

Blood is scientific

Blood is one of the oldest and most used ways to check a person’s wellbeing. As a result, there are thousands of research papers that provide strong scientific evidence linking blood results to a person’s health. So, with blood, you get medically validated information about your health.

Blood is deep

Your blood is deeper than your skin, literally and figuratively. It goes deeper than biometric measurements like heart rate, body temperature, respiratory rate, sleep and such. It reflects your real health based on your metabolism, which is all the vital chemical processes that occur inside your body and help you maintain a healthy life. Meaning, you measure medically recognised health markers (commonly known as biomarkers) such as fats, sugars, proteins, cholesterol, amino acids and more to track your wellbeing. And since blood responds to your daily lifestyle, vis-a-vis what you eat, how much you exercise, how well you sleep, your stress levels and so on, it can track your health real-time. A blood test can show changes in your metabolic health within a couple of weeks.

Blood is detailed

A small blood sample contains numerous data points that can help you keep an eye on multiple aspects of your health. For instance, with the My Nightingale blood test and app — from a single blood draw — you can follow your metabolic health by measuring cholesterol balance, heart age and heart disease risk, inflammation, fatty acid balance, diabetes resistance and type 2 diabetes risk and blood sugar, all at the same time. That’s not all, you also have numerous biomarkers — such as LDL-cholesterol, 
HDL-cholesterol
, VLDL-cholesterol, 
Triglycerides, ApoB
, ApoA1, 
GlycA, 
various fatty acids like Omega- 3 and 6, 
Ketosis, 
BCAAs (amino acids) and more — to give you an even more detailed view of your health.

Blood is dynamic

Your blood constantly changes to reflect your everyday life, even the smallest differences. So, with regular blood tests, you can get constant feedback and actionable data points to improve your health. For instance, say, your blood sugar and diabetes resistance results are poor and you have a higher risk of developing diabetes in the coming years. You can take corrective steps, make lifestyle changes and do a follow-up blood test after a few months to check if things have improved.

It doesn’t always have to be about illnesses. For example, your overall health might be good but you notice that your omega-3% is low. You can try an omega-3-rich diet for a couple of months and see how you’ve progressed. If the results aren’t as good as you expected, you can try out another way. Say, start taking supplements for a few months. This way, you can measure accurately which methods and lifestyle work the best for you.

Each one of us is different than the other, and thus, there is no 'one-size-fits-all' solution to health. No one can give you better feedback about your health than your own body. And blood happens to be the best (and most authentic) tool that can provide you with regular objective feedback and guide you to achieve long-term health.

So, trust your blood.
