1. ApoB
The Plaque-Building Particles
Think of ApoB as a count of the cholesterol-carrying particles moving through your bloodstream. The more particles you have, the more chances they have to stick to your artery walls and build plaque.

2. hsCRP
Your Body’s Fire Alarm
Your body uses inflammation to heal and protect itself. But when inflammation lingers, it can slowly damage your arteries. hsCRP helps measure whether your body's "fire alarm" is staying on.

3. LDL Cholesterol
Cholesterol Delivery
Your body needs cholesterol to build cells and make hormones. LDL is responsible for delivering that cholesterol where it's needed. But when there's too much LDL in your blood, it can contribute to plaque buildup inside your arteries.

4. HDL Cholesterol
Cholesterol Cleanup
HDL helps remove excess cholesterol from your bloodstream and carries it back to your liver, where it can be broken down and removed from your body. This helps keep your arteries clearer over time.

5. Triglycerides
Your Energy Reserve
Your body stores extra calories as triglycerides to use for energy later. But when triglyceride levels stay too high, it can be a sign that your metabolism isn't working as efficiently as it should.

Can I cancel my subscription without fees?
Yes, you can cancel anytime without any fees.
How often is best to test?
We recommend testing every month, but you’re free to skip up to 90 days between tests if you prefer a more quarterly cadence.
When will I receive my order
Kits ship within 1–2 days of placing your order. You’ll receive a tracking email once it ships, and delivery typically takes about 2 business days (around 4 days total from order to arrival).

FAQ
How is Rythm different?
Most blood testing companies charge $500 or more for a single test per biomarker, providing only a one-time snapshot that doesn’t capture your long-term health trends or reflect your true baseline. This approach can lead to missed patterns or even misdiagnoses due to limited data. Rythm takes a different approach, using monthly tracking to build a detailed picture of your health over time. This allows for more accurate insights, better optimization, and a clearer understanding of how your body is evolving.
