Not for emergencies. Call 911 now for chest pain, trouble breathing, fainting or stroke signs. Sometimes you should be seen first. If you have new or worrying symptoms, book a visit before you order tests.
What this panel can show signs of
A result outside the range is a reason to look closer, not a diagnosis. A Passion Health clinician reviews every result and tells you what it means.
A high TSH with a low free T4 means an underactive thyroid; a high TSH with a normal free T4 is a milder form that's often rechecked.
Underactive thyroid care online →A low TSH with a high free T4 means an overactive thyroid.
Overactive thyroid care online →Not in this panel: thyroid antibodies (TPO) or T3. Your clinician adds them when they would change your care.

Questions about this panel
Will I talk to a real clinician?
Yes. A Texas-licensed physician, nurse practitioner or physician assistant reviews every order and result. Visits happen by video or in person. Texas law holds video care to the same standard as an in-person visit (Texas Occupations Code §111.007).
Is Lp(a) a one-time test?
For most adults, yes. The 2026 ACC/AHA guideline recommends measuring Lp(a) at least once in every adult. It is mostly inherited and stays fairly stable, so one test is usually enough unless your clinician has a reason to repeat it.
How long do blood work results take?
Most routine results are back within 1 to 3 business days after your draw; a few specialty tests take up to a week. We message you when results are ready, and a clinician calls you the same day about any critical result.
Why don't you test 100+ biomarkers?
Big counts often include repeats, calculated ratios and markers that rarely change care. Our library shows every marker we offer, marks calculated scores separately, and explains the evidence for each.
What happens if a result is abnormal?
A clinician reviews it. Critical results get a phone call the same day. Other abnormal results are explained with a plan and a recheck date.
