Convenient home collection, accurate, and inexpensive, Saliva Testing provides a true picture of the bioavailable levels of steroid hormones.
Capillary Blood Spot Testing
Capillary Blood Spot Testing offers easy alternative to venous blood draws in the laboratory or doctor's office.
Combination Saliva and Capillary Blood Spot
Combines both Saliva and Capillary Blood Spot test materials in an all-in-one test kit for easy home collection of the major hormone groups— reproductive, adrenal, and thyroid – on the same day at the optimal time.
Female Fertility Profiles I and II
If there is no physical reason for infertility such as tubal damage, many of the different causes of female infertility can be related to hormonal issues. These include ovarian insufficiency, luteal phase deficiency, polycystic ovarian syndrome, thyroid deficiency, and stress. This simple test can identify potentially correctable hormone imbalances and move couples further towards their goals of achieving pregnancy.
CardioMetabolic Risk Profile in Blood Spot
(now includes total and LDL cholesterol). Cardiometabolic risk includes disorders related to obesity and insulin resistance, which can lead to Type 2 diabetes and/or heart disease.
Vitamin D Testing in Blood Spot (25-OH, Total)
Saliva testing is a convenient, inexpensive, and above all, accurate means of testing steroid hormones. Scientific studies have shown a strong correlation between steroid hormone levels in saliva and the amount of hormone in the blood that is active or "bioavailable." It is this fraction of total hormone that is free to enter the target tissues in the brain, uterus, skin, and breasts. Saliva testing can be done anywhere anytime. Testing that relies on blood draws (which need to be done in an office or lab) makes it harder to obtain samples at specific times (such as in the early morning) or multiple times during the day. In addition, hormones in saliva are exceptionally stable and can be stored at room temperature for up to a week without affecting the accuracy of the result. This offers maximum flexibility in sample collection and shipment.
Hormones tested in the saliva profiles include:
Blood Spot testing is the future of blood testing. The process requires only whole capillary blood from a nearly painless finger prick and several tests can be run from a single sample. Blood spot testing provides results on a par with those from serum tests but without the cost and inconvenience of conventional blood drawing. In addition, collection times can be optimized for fasting baseline hormone levels and assessment of HRT dosing and diurnal hormone testing.
Tests offered in the Blood Spot Profiles include:
- Thyroxine (T4), free
- Triiodothyronine (T3), free
- Thyroid Stimulating Hormone (TSH)
- Thyroid Peroxidase Antibodies (TPO)
- Testosterone, total
- Sex Hormone Binding Globulin (SHBG)
- Prostate Specific Antigen (PSA)
- Insulin-like Growth Factor (IGF-1)
- Estradiol (E2)
- Progesterone (Pg)
The Comprehensive Hormone Profile
Putting saliva and blood spot test materials together in one combination kit makes it convenient to collect hormones of the three major glandular systems--reproductive, thyroid, and adrenal--on the same day at the optimal time.
In saliva: Estradiol (E2), Progesterone (Pg), Testosterone (T), DHEA, and the four diurnal Cortisols.
In bloodspot: free T3, free T4, TSH and TPO antibodies
