From the Guidelines
Your cholesterol test results are likely reliable despite consuming jersey milk 2 hours prior to the test, as nonfasting lipid profiles provide acceptably accurate measures for risk calculation. According to the 2019 American College of Cardiology/American Heart Association guideline on the management of blood cholesterol 1, nonfasting total cholesterol and HDL-C levels have fairly similar prognostic value and associations with CVD outcomes as fasting levels. Additionally, the 2015 Annals of Internal Medicine study 1 suggests that a nonfasting lipid profile provides measures of total cholesterol and HDL-C levels that differ little from measures after a 9- to 12-hour fast. However, it's essential to note that consuming fatty foods like jersey milk before testing can cause transient increases in blood lipid levels.
Some key points to consider:
- Nonfasting lipid profiles are generally acceptable for risk calculation and therapeutic decisions 1.
- Fasting lipid measures may be necessary if triglyceride levels are greater than 4.52 mmol/L (>400 mg/dL) or if the purpose is to measure or monitor triglyceride levels 1.
- The efficacy of statins is based on a target dose, not lipid levels, which reduces the need for precise lipid measurements 1.
- Inform your healthcare provider about the milk consumption so they can properly interpret your current results or recommend retesting if necessary.
It's crucial to prioritize your health and consult with your healthcare provider to determine the best course of action regarding your cholesterol test results and any subsequent medical decisions.
From the Research
Reliability of Cholesterol Test Results
- The reliability of cholesterol test results after consuming Jersey milk 2 hours prior to the test is a concern, as dairy products can affect blood lipid concentrations 2.
- However, the impact of a single serving of Jersey milk on cholesterol test results is not directly addressed in the available studies.
- A study on the associations between intake of fermented dairy products and blood lipid concentrations found that cheese intake was positively associated with HDL-C and inversely associated with LDL-C and triglycerides 2.
- Another study developed a method for single-run, simultaneous quantification of cholesterol and triglycerides in each fractionated lipoprotein class, but did not investigate the effect of dairy consumption on test results 3.
- Other studies focused on personalized cholesterol treatment recommendations, the effects of dietary cholesterol and fat saturation on plasma lipoproteins, and the lack of evidence linking dietary cholesterol to cardiovascular disease 4, 5, 6.
- While these studies provide insight into the relationship between dairy consumption and blood lipid concentrations, they do not directly answer the question of whether consuming Jersey milk 2 hours before a cholesterol test affects the reliability of the results.
Factors Influencing Cholesterol Test Results
- Dietary cholesterol and fat saturation can influence plasma lipoprotein concentrations, but the individual effects of these factors can vary depending on the population and diet 5.
- The type and amount of dairy product consumed, as well as the timing of consumption relative to the test, may also impact the results.
- However, without specific studies on the effect of Jersey milk consumption on cholesterol test results, it is difficult to determine the reliability of the results in this case.
