This ultrasensitive estradiol test is recommended for men. The commonly used estradiol test may overestimate estradiol in men. That test uses immunoassay technology that cannot differentiate C-Reactive Protein (involved in inflammation) from estradiol, so it reads the combination of the two as estradiol. This ultrasensitive estradiol test is based on liquid chromatography/mass spectrometry (LC/MS), an assay technology that does not have that limitation. 

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.

This panel includes the two gold standard tests for estradiol and testosterone (Total and Free) that use liquid chromatography/ mass spectrometry for best accuracy and no interactions.

This panel is popular among men who are on testosterone therapy since it offers substantial savings over ordering each of these tests separately : Complete Blood Count (CBC) ,Comprehensive Metabolic Profile ( includes eGFR ), Estradiol UltraSensitive, Testosterone, Total and Free ( Accurate for all testosterone levels, uncapped), Prolactin, Lipids, and Sex Hormone Binding Globulin (SHBG). FASTING IS REQUIRED.

This TRT basic lab test panel includes essential tests (CBC, CMP, ultrasensitive estradiol, and total & free testosterone) to monitor treatment in men on that have been testosterone replacement therapy for a few months. Test included:

• CBC (White and red blood cells, hematocrit, etc)
• CMP (glucose, liver & kidney function, etc)
• Estradiol Ultra Sensitive
• Total Testosterone (LC/MS)
• Free Testosterone (Equilibrium Dialysis)

Fasting is required for proper glucose testing as part of CMP.

This panel is the most inclusive of all offered on the site for men who want a wide picture of their health or who are considering starting testosterone replacement therapy.  It provides a baseline overview of your sex hormones, thyroid gland, adrenal function, metabolic function, cholesterol, prostate, and overall health.  Tests included: 

• CBC
• CMP
• Lipid Panel
• Testosterone
• Total (LC/MS) Estradiol, Ultra Sensitive
• DHEA-s
• TSH
• Free T3
