what blood tests should I ask my PCP for?

To know more about your internal health and make informed decisions about your lifestyle and healthcare, you can consider asking your primary care physician for the following blood tests:

1. Cholesterol levels
2. C-reactive protein (CRP) for inflammation
3. Blood sugar levels
4. HbA1c (Hemoglobin A1c) which reflects average glucose levels over several months

Getting these tests done can enable tracking of important health metrics over time. If you're unable to get comprehensive testing through your doctor due to insurance constraints, there are companies like InsideTracker that offer affordable testing options you could use a couple of times a year and share with your doctor 1. Always remember to have open discussions with your healthcare provider about your desire to monitor your health more closely to make the most of your doctor's visits.

Apolipoprotein B (ApoB) testing is indeed valuable, as highlighted by Peter Attia during his discussion with Andrew Huberman. Dr. Attia recommends measuring ApoB for a better assessment of heart health, and suggests that it should be done early in life, especially if there is a family history of heart disease. He would have ideally had his ApoB measured in his twenties, knowing what he does now 1.

ApoB is a protein that is part of Low-Density Lipoprotein (LDL) particles, and its levels are predictive of cardiovascular function and disease, which can also affect brain health and longevity 2. The number of ApoB particles is more predictive of cardiovascular risk than the cholesterol content within them, making it a more pertinent measurement than just LDL cholesterol levels 3. Therefore, it's a good idea to discuss ApoB testing with your primary care physician to monitor cardiovascular health.
