Cholesterol Analyzer

Total <200, LDL <100 (optimal), HDL 60+ (protective), Triglycerides <150 mg/dL. Total/HDL ratio below 5:1, ideally below 3.5:1.

Total minus HDL. Captures all atherogenic lipoproteins. Target <130 mg/dL. Many experts consider it better than LDL alone.

Cholesterol: divide mg/dL by 38.67. Triglycerides: divide by 88.57. E.g. 200 mg/dL = ~5.17 mmol/L.

LDL (low-density lipoprotein) is often called "bad" cholesterol because it carries cholesterol into artery walls, where it can build up as plaque and narrow the vessels over time. HDL (high-density lipoprotein) is the "good" cholesterol: it ferries excess cholesterol back to the liver for removal, so a higher number is protective. That inversion is why the targets run in opposite directions — you want LDL low (optimal under 100 mg/dL) but HDL high (60 mg/dL or above). It also explains why a low HDL counts as a risk factor rather than a reassuring result. The Cholesterol Analyzer classifies each marker on its own correct scale, flagging high LDL and low HDL separately so you can see exactly which side of your panel needs attention before your next appointment.

The Total/HDL ratio is your total cholesterol divided by your HDL, and it captures the balance between harmful and protective cholesterol in a single figure. A ratio below 3.5:1 is considered optimal, below 5:1 is acceptable, and anything higher signals elevated cardiovascular risk. Because it weighs both numbers together, the ratio can reveal risk that a single value hides — someone with a borderline total reading but very high HDL may still land in a healthy range, while a "normal" total paired with low HDL may not. The analyzer calculates this ratio automatically from your four lipid inputs, alongside the LDL/HDL ratio (optimal under 2.5), and shows each with a color-coded badge so you can interpret the balance, not just the raw totals, at a glance.

HDL, the protective "good" cholesterol, responds well to lifestyle changes. Regular aerobic exercise is one of the most reliable levers — the AHA suggests at least 150 minutes of moderate activity per week to help raise HDL. Stopping smoking, reaching a healthy weight, and replacing trans and refined-carbohydrate calories with sources of unsaturated fat such as olive oil, nuts, and oily fish also tend to nudge HDL upward. Keeping alcohol moderate matters too, since excess can distort your lipid balance. These are exactly the kinds of suggestions the Cholesterol Analyzer surfaces: when your panel shows low HDL or elevated risk, it generates concrete, AHA-aligned recommendations tailored to your numbers. Enter your latest results to see which habits are most likely to move your HDL and overall risk in the right direction.

Traditionally, lipid panels were drawn after a 9-to-12-hour fast because eating temporarily raises triglycerides and can throw off a calculated LDL value. More recent guidance accepts non-fasting samples for routine screening in many people, since Total cholesterol and HDL change little with food and modern labs handle non-fasting results well. Your clinician may still ask you to fast if your triglycerides are high, if LDL is being calculated rather than measured directly, or to keep readings comparable over time. Whichever way your blood was taken, note it when reviewing results, because a recent meal can inflate the triglyceride figure. Once you have your numbers, enter your Total, HDL, LDL, and triglycerides into the Cholesterol Analyzer to classify each value against AHA ranges and see your ratios and overall risk in seconds.

LDL earns the "bad" label because of what it does inside your arteries. Low-density lipoproteins carry cholesterol through the bloodstream and can deposit it in artery walls, where it accumulates as plaque, stiffens and narrows the vessels, and raises the risk of heart attack and stroke. The higher your LDL, the more raw material is available for that build-up, which is why the optimal target sits under 100 mg/dL and readings of 190 and above are rated very high. Non-HDL cholesterol — total minus HDL — goes a step further by capturing every artery-clogging particle, and many specialists consider it an even better predictor than LDL alone. The Cholesterol Analyzer scores your LDL and non-HDL against AHA thresholds together, so you can judge your atherogenic load and decide what to discuss with your doctor.
