Are hormone results from dried plasma different from conventional venipuncture serum?
The hormones test results from dried plasma and conventional venipuncture serum are the same, when you want to measure the “endogenous” level of hormones or when you are supplementing with hormones that are slowly delivered to your body, for example, if you are using the transdermal patch or pellets. The ranges for dried plasma or venipuncture serum/plasma are identical.
However, the test results for hormone levels are different in dried plasma from finger-stick and liquid serum/plasma from venipuncture, when you are supplementing with topical or sublingual hormones. The hormone levels in the capillary blood are much higher as opposed to venipuncture blood when the hormone enters the body through the skin or mucous membranes.
