- ESTRADIOL , Sensitive (LC/MS/MS)$35.69
THIS IS THE MOST AFFORDABLE AND ACCURATE ESTRADIOL TEST IN THE U.S. This ultrasensitive estradiol test is based on liquid chromatography/mass spectrometry (LC/MS), an assay technology that has been shown to more accurately measure estradiol in men and women than the old immunoassay-based test.
Important note: The blood sample is sent out to Quest Diagnostics Nichols Institute San Juan Capistrano, Caifornia. Overnight delivery and testing is performed on Sunday and Friday. Reports are available within 5-7 business days from the time the specimen is collected.
- Ferritin$17.85
Ferritin is a protein that stores iron. Red blood cells need iron to form normally and carry oxygen around your body. Low levels of ferritin lead to iron deficiency anemia, which means you have too few red blood cells. High levels of ferritin can damage your joints, heart, liver, and pancreas.

Renin, also known as angiotensinogenase, is an enzyme that the kidneys produce to regulate aldosterone production. It’s also essential in the renin–angiotensin aldosterone system (RAAS) which maintains your body’s fluid balance and blood pressure. Aldosterone is the primary of several endogenous members of the class of mineralocorticoids in humans. Aldosterone tends to promote sodium and water retention, and lower plasma postasium concentrations.

The volume measurement, or hct blood test, is the proportion of blood that the red blood cells take up. Hemoglobin, on the other hand, is a density or concentration measurement and is expressed in grams per liter or deciliter. (Hemoglobin is, if you will recall from your high school biology, the iron-based protein that transports oxygen.) RBC is a simple count and is usually expressed as the number of million red blood cells that you have per microliter. Usually, hematocrit is three times the amount of hemoglobin.
Testosterone replacement therapy (TRT) increases hematocrit in most men. Read more about how to decrease hematocrit.
NOTE: Hematocrit is also part of the CBC panel, so there is no need to order separately if your order already includes CBC.
