Why You Don't Feel Like Yourself Β· Dr. Ladynez Espinal

Your Complete Optimal Lab Reference

Two numbers matter on every lab report. The standard range is what most laboratories will flag as abnormal. The optimal range is where I want my patients to be. A result can sit comfortably inside the first and nowhere near the second β€” which is how a woman is told she's fine while she feels anything but.

These two targets depend on where you are:
Optimal In standard range, not optimal Outside standard range
Before you fill this in. Estradiol and progesterone targets change depending on your stage, so choose the option above that fits you. If you are still cycling, timing matters: draw estradiol on day 3–5 and progesterone on day 19–22. Free testosterone and pregnenolone are reported differently by different laboratories, so for those two, compare your result against the range printed on your own report. Bring this sheet to your clinician rather than drawing conclusions from it alone.
If you are postmenopausal and not on hormone therapy. Your estradiol, progesterone, and testosterone will read well below these numbers, and that is exactly what your body is doing on its own not a result to be alarmed by. The optimal ranges here are what treatment aims for, not what an untreated body produces after menopause. Everything else on this sheet thyroid, metabolic, vitamin D, B12, iron, liver applies to you the same way regardless.

The optimal ranges on this sheet are the targets I use in my own practice. They are not established clinical cutoffs, and you may hear different numbers from another doctor. This sheet is educational and is not a substitute for evaluation by your own clinician.
