Estradiol, Sensitive Blood Test
Item # LC140244
Highly sensitive estradiol test for those with very low levels
Estradiol is the most abundant form of the hormone estrogen produced by women and (to a lesser degree) men. The liquid chromatography-mass spectrometry blood test is a more sensitive method of testing for estradiol than standard methodology.
|
The sensitive estradiol test uses a liquid chromatography–mass spectrometry (LC-MS) methodology which allows better detection at the lower limits of the range compared to regular immunoassay estradiol test. The LC-MS estradiol test is primarily suggested for situations with very low estrogen levels. It can also be used to monitor E2 levels in both men and woman and may be more accurate compared to immunoassays of estradiol; however, Life Extension® has found the majority of customers do not need this more costly test to get adequate information from the regular immunoassay estradiol test. Instructions Fasting is not required for this test. Take all medications as prescribed. If you are supplementing with any hormones, we suggest taking them approximately 2 hours prior to having your blood drawn to see peak levels. Hormones are best drawn between 8-10 AM. Hormonal contraceptives can interfere with progesterone and estrogen results. Pre-menopausal women: For a 28 day cycle, blood should be drawn on day 21 (day 1 is the day that bleeding begins). For longer or shorter cycles, count 8 days back from the day your next menstruation would start. Post-menopausal women: Blood can be drawn any day of the month. |
