{"product_id":"bioavailable-testosterone","title":"Free Testosterone (Equilibrium Dialysis)","description":"\u003cp\u003eThe direct-measured version of your free testosterone, not the calculated estimate. Equilibrium dialysis, the reference method. Results in 2 weeks.\u003c\/p\u003e\u003cp\u003eYour Core Health Test already includes Total Testosterone as one of its 100+ markers, and uses it together with SHBG to calculate your Free Testosterone. This test measures the free, unbound fraction directly instead, using equilibrium dialysis, the reference method for this measurement, run at Mayo Clinic Laboratories. Useful when your calculated result sits near a threshold or you want the number confirmed rather than derived.\u003c\/p\u003e\u003ch4\u003eWhat is it?\u003c\/h4\u003e\u003cp\u003eThe portion of your testosterone that isn't locked to protein and is free to act on your tissues, measured directly by equilibrium dialysis rather than worked out from your Total Testosterone and SHBG.\u003c\/p\u003e\u003ch4\u003eWhat does it assess?\u003c\/h4\u003e\u003cp\u003eHow much testosterone your body can actually use, measured rather than estimated. Useful when your calculated Free Testosterone sits close to a threshold, since the calculation can be less reliable at the edges.\u003c\/p\u003e\u003ch4\u003eWhat does a low or high reading mean?\u003c\/h4\u003e\u003cp\u003eIn men, a low reading fits symptoms like low energy, low libido, or reduced muscle, and is confirmed with a repeat morning sample. In women, a high reading is the more relevant one. Read alongside your Total Testosterone and SHBG, same as the calculated version.\u003c\/p\u003e\u003cp\u003eThis is a send-out test to Mayo Clinic Laboratories. Results take about 2 weeks, longer than your other CHT markers.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eSave $22 when bundled.\u003c\/em\u003e\u003c\/p\u003e","brand":"PROTOCOL","offers":[{"title":"Default","offer_id":51188979302623,"sku":"FT-ED-ADDON","price":216.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0806\/5744\/9183\/files\/bioavailable-testosterone-product.png?v=1786453043","url":"https:\/\/www.protocolhealth.sg\/products\/bioavailable-testosterone","provider":"PROTOCOL","version":"1.0","type":"link"}
