I am having trouble collecting enough blood, what should I do?

For Blood Tests:

Please aim to fill the tube to the upper line if possible. The tips below might help you collect your sample.

If you have managed to fill the tube approximately half way, we would advise sending the sample back to the lab for testing. If there is not enough blood to provide a test result, we will reach out to you to discuss this.

If you have used all of your lancets and have not managed to fill the sample tube to at least the halfway mark, please let us know as other forms of sample collection may be more suitable for you.
Here are some tips to help:

1. Drink a glass of water. Being well hydrated will make it easier to collect your sample.
2. Shower before you collect your sample, or run your hands under warm water for a few minutes, as heat improves blood flow.
3. Do some light exercise (move around, go for a walk, etc.) to get the blood flowing.
4. Make sure your arm is below your heart level - let gravity do some of the work.
5. Nails that are too long can make it difficult to collect a sample.
6. Review the blood collection instructions and video (link here)

Hard skin and calluses can also make it more difficult to collect a sample, you can read more about this here (link here)


Do you have a blood test that checks everything?

Unfortunately, there is no one test for everything. Even in hospitals, multiple tests are required for a comprehensive analysis.  KnowingLabs offers a wide range of tests through our partner laboratories that address many health concerns. 
If you live outside the US or have additional questions, we are happy to answer any questions you might have about our tests or sample collection kits. You can contact our customer support team 24/7 by clicking here (link)
