5 Ways Bloodwork Can Help Clarify PMOS Symptoms†
PMOS, Polyendocrine Metabolic Ovarian Syndrome, (previously referred to as PCOS) can be more than irregular periods and ovarian cysts. It can affect your hormones, metabolism, energy, skin, hair, and long-term health, and the patterns aren't always easy to spot. Painless, at-home blood testing with Rythm tracks the markers that help you better understand PMOS-related signals and broader patterns over time.

ANDROGENS
01
Your testosterone isn't the whole picture.
Acne, hair shedding, oily skin, and irregular cycles often point back to androgens. But total testosterone is only part of the story. SHBG can change how much testosterone is actually available to your tissues, and free testosterone can add useful context. Rythm tracks all three together so you can see what your androgen pattern actually looks like.

CYCLE PATTERNS
02
Your cycle isn’t random. It’s a signal.
PMOS/PCOS cycles aren't predictable, so a single hormone test rarely tells the full story. Rythm tracks both estradiol and progesterone, because they mean more when tracked together over time. With enough trended data, what looked random starts to become readable.

METABOLIC HEALTH
03
PMOS/PCOS affects your metabolism, not just your ovaries.
PCOS was renamed PMOS because metabolic health is just as much a part of the condition as your cycle. Rythm tracks fructosamine, ApoB, LDL, HDL, triglycerides, and hsCRP so you can see how your cardiometabolic health is trending over time.

WHAT YOUR THYROID AFFECTS
04
Fatigue? Weight loss? Weight gain? It could be your thyroid.
Your thyroid can cause fatigue, weight changes, hair shedding, mood swings, and poor sleep. So can PMOS. So can perimenopause, postpartum changes, and stress. Tracking TSH and free T3 alongside your PCOS markers helps you tell whether your thyroid is part of the story, or whether your symptoms might have other causes.

NUTRIENTS & ENERGY
05
Is it PMOS/PCOS? Or a nutrient gap?
People with PMOS often get told that every symptom traces back to hormones. It doesn't always. Low iron drives fatigue and hair shedding. Low vitamin D drives low mood and aches. Low B12 drives brain fog. Rythm tracks ferritin, vitamin D, B12, hemoglobin, hematocrit, and hsCRP alongside your hormone markers, so you can see the full picture and build an actionable plan with your clinician.

† Disclaimer: Rythm does not diagnose PMOS. PMOS is diagnosed clinically using symptoms, history, and diagnostic criteria that may include hyperandrogenism, ovulatory dysfunction, ovarian morphology, AMH, and exclusion of other causes. Rythm helps track hormone, metabolic, thyroid, nutrient, and inflammation markers that may be relevant to PMOS-related patterns.

What our customers with hormone disorders 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 thyroidissues and I hear nothing back, good or bad. Rythm gives a detailed report and recommendations for improvement. I highly recommend!

It shows EVERYTHING
First time doing an at home blood lab, I literally can’t believe it was so fast. I got my kit within a few days of ordering and my results were ready after sending it back in 2 days. It shows EVERYTHING. I also saw my hormone levels related to my period which explains why they’re so severe!

I can take control of my lab data!
I love Rythm- it has allowed me to not rely on my MD to help evaluate where my sex and thyroid hormones are at. I feel like I am in control of my health and not at the mercy of an MD arguing with me about whether or not a lab test is valued or relevant. Thank you Rythm Health!

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.

Rythm provides actionable suggestions and tips to help you optimize each biomarker
Is Rythm HIPAA aligned?
Yes, Rythm is HIPAA aligned. Your data is securely stored and handled in accordance with strict privacy and security standards.
Can I cancel anytime without fees?
