Vitamin B12 is essential for most body systems, particularly in haematology with the manufacture of blood cells and hence healthy function of the organism as a whole, including the nervous system. Symptoms of low vitamin B12 are abundant, including tiredness, lack of energy, headaches and many others.\u003c\/p\u003e\n\u003cp\u003eThis test measures both active and total levels of Vitamin B12\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTotal B12\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003erefers to the measurement of all forms of vitamin B12 present in the blood. This includes both active B12 (methylcobalamin and adenosylcobalamin) and inactive B12 forms (such as cyanocobalamin). The measurement of total B12 provides an overall picture of the total B12 content in the bloodstream, regardless of whether the B12 forms are actively available for body use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eActive B12\u003c\/strong\u003e, also known as cobalamin, refers to the biologically active forms of vitamin B12 that are immediately available for the body to use. The two primary active forms are methylcobalamin and adenosylcobalamin. These active forms play essential roles in various physiological processes, particularly in energy metabolism and nerve function. Active B12 is measured up to concentration of 150. \u003c\/p\u003e\n\u003ch3\u003eWhy it is important to measure both.\u003c\/h3\u003e\n\u003cp\u003eThe distinction between total B12 and active B12 is crucial because not all forms of B12 are biologically active or readily usable by the body. Cyanocobalamin, for example, is an inactive form of B12 that requires conversion into active forms before the body can utilise it. Methylcobalamin and adenosylcobalamin are already in their active forms and can be directly utilized by cells.\u003c\/p\u003e\n\u003cp\u003eIn some cases, only total B12 levels are measured, which may not give a complete assessment of B12 status. It is often beneficial to measure active B12 levels (or other markers like free B12\/holotranscobalamin) to better understand the body`s immediate access to functional B12.\u003c\/p\u003e\n\u003cp\u003eThis test measures both forms.\u003c\/p\u003e\n\u003cp\u003e\u003ca id=\"biomarkers_anchor\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003e2 BIOMARKERS\u003c\/h3\u003e\n\u003cdiv class=\"funky_list\"\u003e\n\u003col role=\"list\"\u003e\n\u003cli\u003e\n\u003ch4\u003eVITAMINS\u003c\/h4\u003e\n\u003cp\u003e- Total Vitamin B12\u003cbr\u003e- Active Vitamin B12\u003cbr\u003e- Turnaround time for this test is up to 3 days for active B12.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Ageless Medical Clinic","offers":[{"title":"Default Title","offer_id":55615564317013,"sku":null,"price":69.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0825\/6982\/2549\/files\/HomeBloodTestingKitBox_4aecba2f-f81e-46b6-9319-25d86954e28e.png?v=1793544165","url":"https:\/\/www.agelessmedical.co.uk\/products\/vitamin-b12-home-blood-testing-kit","provider":"Ageless Medical Clinic","version":"1.0","type":"link"}
