5 Ways Your Bloodwork Can Explain Your Thyroid Symptoms†

Thyroid symptoms are sneaky: Fatigue, weight changes, hair shedding, mood swings, sleep issues. They sound like a lot of other things, which is why so many women go years without knowing their thyroid is part of the story. Rythm tracks the markers help you follow thyroid-related signals and broader patterns over time.

THE SIGNS

01

Fatigue, hair loss, weight gain? Check your thyroid-related markers

Tired. Cold. Foggy. Shedding hair. Gaining weight for no clear reason. These get written off as stress, age, or hormones every day. Sometimes that's right. Sometimes it's your thyroid. Tracking TSH and free T3 monthly helps show whether thyroid markers are stable, shifting or worth discussing with your clinician.

THE THYROID SIGNAL

02

TSH & Free T3 show how hard your thyroid is working

TSH is the signal your brain sends when your thyroid isn't keeping up. Free T3 is one form of active thyroid hormone available in circulation. Tracking both gives you a real read on how your thyroid is doing, and monthly testing is how you spot a trend before symptoms catch up.

THE OVERLAP

03

Check for  deficiencies that mimic thyroid issues

Low iron causes fatigue. Low vitamin D causes mood dips and aches. Low B12 causes brain fog. These are some of the most common deficiencies in women, and they look almost identical to a thyroid issue. Rythm tracks ferritin, vitamin D, B12, and hemoglobin alongside your thyroid markers, so you can see whether it's your thyroid, a deficiency, or both.

WHAT YOUR THYROID AFFECTS

04

See how your thyroid is shaping the rest of your body

Your thyroid touches almost everything: your cholesterol, your cycle, your inflammation, your hormones. When thyroid function shifts, these markers may shift too. Rythm tracks LDL, triglycerides, hsCRP, estradiol, and SHBG alongside TSH and free T3, so you can see how your thyroid is showing up across your whole body, not just on a single lab.

MONITORING & MEDICATION

05

Use bloodwork to inform thyroid treatment

Dialing your thyroid treatment.can take months. Standard testing usually happens every three to six months, which is a long time to feel off and not know why.  Rythm’s monthly testing can help you better understand your own biomarkers, so you can see how you're responding to your current treatment in real time, and walk into your next appointment feeling empowered with data.

It does not replace a complete thyroid evaluation, diagnosis, or treatment plan from a licensed clinician. Some people may need additional testing, such as free T4, thyroid antibodies, or other clinician-directed labs, to fully evaluate thyroid function and symptoms.

What our customers with thyroid symptoms are saying

Convenient & Useful

The convenience of doing it at home is great but the feedback from the results is even better. I get blood work done bi-annually at the clinic for my thyroid issues and I hear nothing back, good or bad. Rythm gives a detailed report and recommendations for improvement. I highly recommend!

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.
