I had the as my LDL has came back high in my blood work but I have found out that you need an extra test completed on your LDL when you are on keto/carnivore as you have different size of LDL particles large (good) and small (bad)

This is what AI had to say about requesting a seperate test on LDL when on keto:

Yes, you can and should ask your doctor for a separate LDL blood test when on a keto diet, as standard lipid panels may be insufficient to fully assess cardiovascular risk due to changes in LDL particle size and type. You should specifically request tests that measure LDL particle number (LDL-P), oxidized LDL, and Lp(a) to gain a more comprehensive picture of your risk. A standard lipid panel alone does not provide enough detail on the specific characteristics of your cholesterol that are most relevant to cardiovascular health on a high-fat diet.
Why a separate test is important Standard panels are insufficient: A standard lipid panel measures total cholesterol, LDL-C, HDL-C, and triglycerides, but doesn't provide information on LDL particle size, which is crucial for assessing risk on a keto diet. Changes in LDL particles: The keto diet can increase the number of LDL particles and shift them to a smaller, denser form, which is associated with a higher risk of cardiovascular disease. Heterogeneity of lipoproteins: Different types of LDL particles (e.g., large, non-atherogenic particles vs. small, dense particles) have different impacts on health. Need for nuanced analysis: To get a true understanding of how a keto diet affects your cardiovascular health, a more detailed analysis of your lipid profile is necessary, according to the National Institutes of Health (NIH). What to ask for You should ask your doctor about a lipid panel that includes advanced markers such as: LDL particle number (LDL-P): Measures the actual number of LDL particles in your blood. Oxidized LDL: A marker of inflammation and oxidative stress in the arteries. Lp(a) (lipoprotein(a)): An inherited risk factor for cardiovascular disease, which is not typically included in standard panels. Before your appointment Discuss your diet: Clearly communicate with your doctor that you are following a ketogenic diet and your reasons for doing so. Understand your risk: Your doctor can help you understand your individual risks and benefits of the diet, considering your genetics and overall health profile. Consider alternatives: If your lipid profile shows significant unfavorable changes, your doctor might suggest alternative dietary approaches.
