Notes and caveats
Hims & Hers Labs: Hims & Hers also offers other services that are not covered or evaluated here, including telehealth care and prescription treatment. The company says its Labs action plan can include access to personalized treatment plans if a provider deems them appropriate. Only the testing is described here.
Lifeforce: Lifeforce also offers other services that are not covered or evaluated here, including clinician-managed treatment and prescriptions. Its testing is sold as part of that clinician-led membership rather than as a stand-alone test, so it may not suit someone who only wants a test. Lifeforce's page lists insulin with an asterisk it does not explain, so it is shown as Not listed.
Mito Health: Mito sells tiered panels (Essential, Core, Pro, Ultra). "Larger panels" means the marker is added in a higher tier.
Superpower: Superpower says its care team can also help with treatments; those services are not covered or evaluated here. Only the testing is described. Superpower's biomarker page lists Lp(a) and insulin both as included and in add-on or alternate panels; confirm before buying.
Ulta Lab Tests: Ulta Lab Tests' pages could not be loaded for this check, so no marker is confirmed here. Check its catalog directly.
3. Why people ask about these markers
Neutral background only. Whether any test is appropriate for you depends on your history; a licensed clinician can advise.
- ApoB (apolipoprotein B)
- ApoB is a protein carried on LDL and other cholesterol-carrying particles. Guidelines discuss this marker in cardiovascular risk assessment. What a result means for you is a question for a licensed clinician. Evidence note: Discussed in a major US guideline as an optional measurement for selected adults. Source: Grundy SM et al. 2018 AHA/ACC/AACVPR/AAPA/ABC/ACPM/ADA/AGS/APhA/ASPC/NLA/PCNA Guideline on the Management of Blood Cholesterol: A Report of the American College of Cardiology/American Heart Association Task Force on Clinical Practice Guidelines. Circulation 2019
- Lp(a) (lipoprotein(a))
- Lp(a) is a cholesterol-carrying particle. Guidelines discuss this marker in cardiovascular risk assessment. What a result means for you is a question for a licensed clinician. Evidence note: Discussed in a major US guideline as an optional measurement for selected adults. Source: Grundy SM et al. 2018 AHA/ACC/AACVPR/AAPA/ABC/ACPM/ADA/AGS/APhA/ASPC/NLA/PCNA Guideline on the Management of Blood Cholesterol: A Report of the American College of Cardiology/American Heart Association Task Force on Clinical Practice Guidelines. Circulation 2019
- hsCRP (high-sensitivity C-reactive protein)
- hsCRP is a blood marker of inflammation. Guidelines discuss this marker in cardiovascular risk assessment. What a result means for you is a question for a licensed clinician. Evidence note: Discussed in a major US guideline as an optional measurement for selected adults. It is not specific to the heart and can change with short-term illness.

Circulation 2019
- HbA1c (hemoglobin A1c)
- HbA1c reflects average blood glucose over roughly the past few months. Guidelines discuss this marker in the evaluation of blood glucose and diabetes. What a result means for you is a question for a licensed clinician. Evidence note: Discussed in a major clinical guideline. Source: American Diabetes Association Professional Practice Committee. 2. Diagnosis and Classification of Diabetes: Standards of Care in Diabetes-2026. Diabetes Care 2026
- Insulin (fasting)
- Fasting insulin measures how much insulin is in the blood after an overnight fast. It is not among the measures the guideline cited here relies on. What a result means for you is a question for a licensed clinician. Evidence note: Not rated. Interpretation is not standardized.

- Testosterone (total and free)
- Testosterone is a hormone marker commonly included in consumer blood panels. Interpretation of a result and any follow-up belong with a licensed clinician. We do not cover or evaluate treatments.

4. Questions to ask before you buy
- What does a retest cost? Compare the price per test over a year, not just the first test. Some plans include a follow-up; others charge per draw.
- What exactly is included? Check which markers are in the base panel and which are add-ons, plus any fees for at-home draws, physician orders or shipping.
- Are results reviewed by a clinician? Ask who reviews results, whether you can talk to them, what it costs, and what happens if a result is critical.
- How is my data handled? Read the privacy policy: who can see results, whether data is shared or sold, and how to delete it.
- Membership or pay-per-test? A membership may bundle tests, reviews and an app; pay-per-test lets you order only what you want. Neither is right for everyone.
- What are the cancellation and refund terms? Check auto-renewal, how to cancel, and whether unused tests or kits are refundable.
