Blood tests can take time and money through a doctors office. I love using OmegaQuant because it's so much less expensive and can be done from home. They email you your test results and let you know if you're in the optimal range. They have tests for vitamin D, vitamin B12, omega 3:6, prenatal DHA, breastmilk test, blood sugar test and even a test for pets!
