This at-home saliva panel measures five hormones and maps a full day of cortisol. Estradiol, progesterone, testosterone and DHEA-S, plus cortisol collected four times across the day to show your daily rhythm rather than a single reading.
| Laboratory | ZRT Laboratory |
| Measures | Estradiol, progesterone, testosterone, DHEA-S, cortisol at 4 time points |
| Collection | Saliva, at home, across one day |
| Results | About 2 weeks |
| Included | One follow-up consultation with a Flourish nutrition professional |
| Not suitable for | Sublingual hormone users. See below. |
Flourish sells two smaller kits that this one combines.
| Hormone Saliva Kit | 5 hormones, 1 morning cortisol |
| 4-Point Diurnal Cortisol | Cortisol only, 4 samples across the day |
| This panel | Both, in one kit, on one collection day, for less than the two bought separately |
They are not independent systems, and ZRT's own data sheets say so.
Cortisol is the body's stress hormone. As part of the fight-or-flight response it temporarily shuts down processes that are not immediately needed, and ZRT names hormone production among them. In the male hormone data sheet the point is made directly: some practitioners find that testosterone therapy is of little benefit unless cortisol is addressed first, which is why ZRT recommends a complete hormone profile before starting any hormone replacement.
Looking at estradiol, progesterone, testosterone and DHEA-S while your cortisol is high, and not knowing your cortisol is high, is how people end up chasing a downstream number.
Cortisol is not meant to be flat. It normally peaks shortly after waking and declines through the day to its lowest point at bedtime. A single reading is one point on that curve. Four readings, taken at set times, show the shape.
The shape is where the useful pattern lives. Two people can have the same morning cortisol and completely different days.
Steroid hormones in blood are largely bound to carrier proteins and in that form are not available to your tissues. Saliva measures the unbound, bioavailable fraction, which ZRT describes as relating more closely to symptoms of excess or deficiency and as a good option for monitoring hormone therapy.
It is also non-invasive, collected at home, and well suited to taking several samples across a single day.
ZRT states that saliva testing is not appropriate for sublingual hormone users, because the hormone contaminates the sample directly, and that blood spot testing is the preferred option for these patients.
Flourish compounds sublingual hormones, so we would rather tell you this before you order than after your result comes back unreadable. Call 405-751-3333 and we will route you to the right method.
A wellness and monitoring tool, not a diagnostic test, and not a replacement for evaluation by your physician. It does not diagnose any condition. This saliva panel also does not include thyroid hormones.
Your purchase includes a one-on-one follow-up consultation with a Flourish nutrition professional to review your results and discuss next steps. During that conversation you can expect to:
Laboratory testing provides data. Understanding how it relates to your symptoms is the part that changes anything.
What does this panel measure?
Estradiol, progesterone, testosterone, DHEA-S, and cortisol at four time points across one day.
How is this different from the standard hormone saliva kit?
Same five hormones. This one measures cortisol four times instead of once, so it shows your daily cortisol rhythm.
How is this different from the 4-point cortisol kit?
That kit is cortisol only. This adds the four sex and adrenal hormones.
Why does a hormone panel include cortisol at all?
Because cortisol can suppress the production of other hormones as part of the stress response. Reading sex hormones without knowing what cortisol is doing can be misleading.
Do I collect everything on the same day?
Yes. One collection day, with the cortisol samples at set times. Full instructions come in the kit.
Does it include thyroid?
No. ZRT's saliva profiles do not include thyroid hormones.
Can I use this to monitor hormone therapy?
It depends on the form you use. If you use a sublingual preparation, saliva is not the right method and ZRT recommends blood spot instead. Call 405-751-3333 before ordering.
Is a doctor's order required?
No. You can buy the kit and receive your results without an appointment, and a consultation with our nutrition team is included.
How long do results take?
About two weeks after the laboratory receives your samples.
If you are not sure it is the right one for you, contact the Flourish team or call 405-751-3333 first. You can also explore our Women's Hormones and Men's Hormones resources.
