Rythm VS Quest blood tests

I think I'm going to look into RequestATest and Fitomics. I'm mostly interested in liver/kidney health, testosterone/estrodiol levels, and IGF1. The more I think about it, the less happy I become with Rythm.

Lab blood work intrinsically isn't like a hair cut or finding a deal on a new pair of pants where close counts and cost is an attenuator and sadly I know that your measure of people is accurate. LOL

Why bother at all with lab work of any kind if convenience outweighs accuracy?

Doesn't make any sense at all to me.

But again, I know you're right. People are super often willing to be willfully ignorant and in denial - to what end I do not know but it is factual to accept that.

The difference between an accurate HbA1c and an inaccurate one can be life changing.

But people proved themselves buying rocks for pets in the 70s so there's that.

You can also look at Labcorp directly for the tests you mention fwiw and forgo the "middle man." I do not know if Quest offers the same service. I must say though that what @Calm Logicreports regarding Fitomics sounds like it might be the most cost-efficient AND accurate way to go if one plans on having multiple labs done monthly or bi-monthly. Having them done every quarter starts to become more of a question for me subscription-wise. Even still, I think the math works in Fitomics favor. I'll make a spreadsheet in my spare time to compare.

🙂

EDIT: I just perused Fitomics website - at least the one that pops up first in my Google search and I don't find it intuitive enough for me to make a comparison to RequestATest which is basically an online menu of hundreds of easily reviewable and readily available bloodwork, urine, etc tests. I don't mean at all to be a knock on Fitomics. RATHER - I have to notice and report what CONVENIENCE means to me personally (as the light bulb goes off in my own head) - I do not want to search and read. I want my options with inherently accurate results handed to me on a very obvious platter and I am willing to pay for that.

This edit is meant only for clarity-sake - again - as it is also becoming clearer to me.

I just did the same and I agree, their site is not very informative. But I did find a large thread here that explains it in more detail. I think I'll be going with Fitomics. Already cancelled my Rythm subscription. Their accuracy was just too far off, even for just tracking trends. I am going to be starting a Tesa+Ipa cycle along with Enclomiphene, so I will be getting monthly testing for a while to keep an eye on my test, estradiol, and IGF1 levels. Also, it never hurts to watch kidney and liver enzymes while researching.

I have been running that same exact stack (+ Tirz/Survo) since August and have been very pleased with the results on all the same measures you are looking at. For cardio-concerns, I also run a lipid panel and ApoB routinely. A CRP test is good for liver if you were not aware. Best of luck to you!
 
A CBC test at LabCorp through Fitomics is less than $3. So it is crazy Fitomics doesn't publish their lab prices themselves. Only $5 for a CMP, $5 for an A1c, and $7 for a lipid panel. The biggest savings includes IGF-1 at $14 and testosterone free and total at $22 (using the LabCorp option).

But I just noticed MyBlood.AI (GoodLabs) has some great prices, including on hormone tests using Quest , often better than the cheapest options at Fitomics.

A price comparison of various lab test prices at different sites (including Fitomics, OwnYourLabs, DrSays, MyBlood.AI (GoodLabs), Rupa Health, JansonHealth, Marek, Quest's website, and LabCorp's website), posted at the Fitomics thread:

Blood Test Order Sites Pricing - Snapshot (Updated 2026MAR02)

docs.google.com

Also attached as a PDF (but the above spreadsheet is updated every so often by the author, who can be contacted at Discord to report errors).

Fitomics Coupon Codes:

FIRST10 (10% off first lab order)

DISCORDLABS (5% off lab orders)
 
MyBlood.AI has an $8 draw fee for LabCorp and a $12 draw fee for Quest. No draw fees with Fitomics since that is included with the subscription.

The hack with Fitomics is to order your tests for up to the next six months. You don't need an active membership to get test results back. To avoid the monthly renewal, you can cancel right after joining, which keeps your membership active until the end of the subscription month.

Fun with Gemini, comparing MyBlood.AI (GoodLabs) to Fitomics (with some errors and omissions, so best to check the spreadsheet comparing various lab sites):

In case it matters to you, Rhythm is not a covered entity under HIPAA, whereas Quest is.

And where you order tests to be performed by LabCorp or Quest but that order is placed through a discount online vendor, and that vendor reports results back to you, that vendor typically also isn’t a HIPAA covered entity. Lots of privacy risks depending on the means used to get testing.

My results with Fitomics also show up at the website of Quest Diagnostics. Not for LabCorp though, which was months ago.

By the way, Quest is still hounding me down for $57 from 2018. I thought I paid it since it was a pre-paid test I ordered at Quest's website, but the lab tech iust reminded me it is still due. I then looked into it and my FSA reversed the $57 months later. Bastards.

I was really interested in the large batch of tests at Function Health done twice a year for $365. It wasn’t the cost that concerned me, but the unknown privacy risks.

So for now, I’m sticking with biannual tests through my PCP. They’re covered by insurance, but not as varied as those offered by Function. Perhaps the hypochondriac in me shouldn’t get those Function tests anyway. 🤣
 
I'm the only person in the waiting room at my Labcorp. Shocking. I guess because of the holidays. But they still are taking their slow-ass time, even with an appointment.

If I was using insurance, I would try a hospital here that usually has no wait.
 
Already got the blood results from the draw at Labcorp, less than 24 hours ago. But I didn't order anything special like hormone tests. I know IGF from Labcorp takes a full week.

And I just remembered the hospital here doesn't provide online results for three days, to give time for the doc to see the results first.
 
Finally signed up for fitnomics. Since I just had everything else done, I just went with an IGF-1 and CMB for $17. I recently started Tesa/IPA so I need to get them done. Then in a month or two I'll need to get another testosterone test for the enclomiphene I'm starting next week. This is a game changer to just get whatever tests I need whenever I want for dirt cheap! It's going to be so easy to keep track on everything. It's crazy! Thanks for the heads up about it.

Please let me know how it goes. I'm looking for easy, private, and accurate blood testing places myself.

Can I DM you about the Enclomiphene?

Will do. And of course.
 
Update on my experiences with Siphox and Rythm.

Siphox continues to disappoint. They literally take weeks to deliver a test after ordering. At least 1/2 the tests I've sent in have to be repeated. The latest incident was when my wife and I both sent in tests. We both received confirmation that our tests were recieved at the lab. 3 days later we both received an email saying that the tests had been lost in the mail. I contacted them and asked what was going on. They said that the lab 'forgot' to mark them as received but rest assured, they are being processed at the lab, and they would send us each a free test to make up for it. Ok.

3 weeks after they received the samples, still no results so I asked what the status of the tests were. "those samples are now expired from being too old." What? When I send in a test, I want to know what the markers are at that point in time as I often change dosing immediately after the test. Now it's useless for me to take another test because my markers are going to be different. If I ever get through all the 'free' tests they've sent me to make up for errors, I'll not be sending them any more business.

Rythm on the other had has been stellar in getting tests delivered to me within a couple days of ordering and results from the tests in under a week, once within 3 days. Until something changes, I'll send them all my business.
 
I had high hopes for Rhythm and Siphox, but turns out capillary draw isn’t reliable or comparable like venous draw. I don’t plan to do either again unless new information comes forward, I’ll just stick with Labcorp.
 
Man, Rythm is killing it. I dropped a sample Monday morning to FedEx. I got results in 36 hours. One of my kids dropped a sample Tuesday morning and got results in 31 hours.

Suck it Siphox.
 
For those following, Rythm has added additional markers to their test at no extra charge:
