Wells Pharmacy is a provider of ZRT laboratory’s non-invasive and easy to use home collection test kits for the assessments of:

Sexual Hormones:

  • Estradiol (E2)
  • Progesterone
  • Testosterone
  • DHEA-S

Sex Hormone Metabolites:

  • Hormones that don’t break down properly in the body can increase the risk for certain cancers
  • Reveals what the body does (metabolize, or breakdown) hormones
  • Hormones are carcinogenic if theydon’t break down properly.
  • Consider testing in cases
    a) Family history of hormone-dependent cancers- breast or prostate
    b) Symptoms of estrogen dominance while on physiological replacement dosages of therapy
    c) Normal saliva cortisol levels but still have symptoms of adrenal dysfunction

Thyroid Balance:

  • Thyroxine (T4), free
  • Triiodothyronine (T3), free
  • Thyroid Stimulating Hormone (TSH)
  • Thyroid PeroxidaseAntibodies (TPO)

Neurotransmitters (NT):

  • Identify suboptimal neurotransmitter levels
  • Dys-regulated nervous system, NT related health issues
    a)     Anxiety  & Depression
    b)     Chronic fatigue
    c)     Impulsivity
    d)     Insomnia
    e)     PMS or PMDD

Essential Elements:

  • Nutritional elements that support brain health
  • Nutritional elements that support thyroid health

Heavy Metals:

  • Heavy metals are damaging to brain health
  • Disrupts neurotransmitter function
  • Create oxidative stress that is detrimental to nerve cells, brain function

Cortisol Levels (Stress):

  • Impairs immunity
  • Affects fertility
  • Ability to counter inflammatory conditions such as endometriosis

Insulin-like Growth Factor (IGF-1) Somatomedin C

Insulin, fasting

Cholesterol (CH), total

C-Reactive Protein, High Sensitivity

Vitamin D

  • Total
  • 25-OH Vitamin D2
  • 25-OH Vitamin D3

Fertility Testing that identifies factors affecting fertility

  • Low Progesterone
  • PCOS (Polycystic OvarianSyndrome)
  • Thyroid Disorders
  • Low Egg Reserve
  • Stress

Serum testing is what most people are familiar with when they think of testing. This is the kind of test where blood sample is drawn from your veins. There are different testing methodologies for assessing analytes, each with its own advantages and limitations.  

ZRT test kits are designed to match analytes to the most suitable sample type. We will discuss four testing methodologies (sample types).


  • Identifies bio available (free or unbound)hormones
  • Monitoring hormone replacement therapy given orally,topically, vaginally, or via pellets
  • Non-invasive
  • Collecting multiple samples during a day
  • Not suitable for
    a) Monitoring sublingual/troche hormone replacement
    b) Patients with dry mouth, e.g., due to Sjogren’s syndrome

Dried Blood Spot

  • Assessing interstitial tissue/capillary hormone levels or A1C
  • Assessing total circulating hormone levels (free plus protein bound)
  • Toxic and nutritional elements requiring a whole blood sample (lead, magnesium, vitamin D.
  • Avoiding a trip to the phlebotomist
  • Suitable for monitoring hormone replacement therapy (oral, sublingual, pellet, topical and vaginal)

Dried Urine Testing

  • Painless, non-invasive, and simple alternative to all-day urine collection in a jug or test that requires multiple collections during a day such as cortisol levels
  • Toxic element exposure
  • Iodine/selenium sufficiency for thyroid health
  • Steroid hormone metabolites for breast cancer risk assesment
  • Not suitable for topical or intra vaginal hormone replacement therapy

Serum Testing

  • Broadly accepted method for measuring analytes that circulate in the bloodstream
  • Covered by most insurance with a doctor’s order
  • Is not a measure of hormones delivered to the tissues
  • Suitable for
    a)     Assessing thyroid health
    b)     Assessing total circulating endogenous hormone levels (free +protein-bound) 
    c)     Monitoring BHRT (sublingual, patch, pellet)
  • Not Suitable for
    a)     Monitoring topical BHRT (underestimates tissue uptake)
    b)     Monitoring oral BHRT (metabolites interfere with testing)
    c)     Assessing analytes that require a whole blood sample (HbA1c and blood lead)
