1. Descriere general\u0103<\/b><\/p>\n
Vitamina B12 (cobalamina) este o vitamin\u0103 hidrosolubil\u0103, esen\u021bial\u0103 pentru regenerarea celular\u0103 \u0219i metabolismul energetic. Aceasta este implicat\u0103 \u00een formarea corect\u0103 a eritrocitelor, globulele ro\u0219ii ale s\u00e2ngelui, sinteza ADN-ului \u0219i func\u021bionarea normal\u0103 a sistemului nervos, av\u00e2nd rol \u00een protec\u021bia fibrelor nervoase.
\n
Principalele surse ale vitaminei B12 sunt produsele de origine animal\u0103, precum carnea, \u00een special carnea ro\u0219ie \u0219i organele, pe\u0219tele, fructele de mare, lactatele \u0219i ou\u0103le. Sursele vegetale includ alimente \u00eembog\u0103\u021bite cu vitamina B12, cum ar fi cerealele fortificate sau laptele vegetal fortificat.
\n
Vitamina B12 se absoarbe cu ajutorul unei proteine specifice produs\u0103 la nivelul stomacului, numit\u0103 factor intrinsec. Factorul intrinsec protejeaz\u0103 vitamina B12 de acidul din stomac \u0219i faciliteaz\u0103 transportul \u0219i absorb\u021bia acesteia \u00een organism.
\n
Determinarea vitaminei B12 \u00een s\u00e2nge evalueaz\u0103 nivelul circulant al vitaminei \u0219i este util\u0103 \u00een diagnosticul deficitului de B12, o cauz\u0103 frecvent\u0103 de anemie megaloblastic\u0103 \u0219i simptome neurologice (parestezii, tulbur\u0103ri de mers, tulbur\u0103ri cognitive).<\/p>\n

Analize complementare<\/b> Vitamina B12 are rol fundamental \u00een sinteza de ADN, formarea globulelor ro\u0219ii \u0219i func\u021bionarea optim\u0103 a sistemului nervos. Deficitul poate determina anemie megaloblastic\u0103 \u0219i neuropatii periferice. Analiza este indicat\u0103 pentru diagnosticul deficitului de vitamina B12, \u00een evaluarea anemiilor megaloblastice \u0219i a tulbur\u0103rilor neurologice, precum \u0219i pentru monitorizarea pacien\u021bilor cu risc de deficit (aport alimentar insuficient, malabsorb\u021bie, chirurgie bariatric\u0103).<\/p>\n","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false,"inline_featured_image":false},"product_brand":[],"product_cat":[1209,3183,2876],"product_tag":[3905,3980,3977,3979,3978,3981],"class_list":{"0":"post-26539","1":"product","2":"type-product","3":"status-publish","5":"product_cat-analize","6":"product_cat-diverse-vitamine-oligoelemente","7":"product_cat-serviciu-laborator","8":"product_tag-anemie-megaloblastica","9":"product_tag-anemie-pernicioasa","10":"product_tag-b12","11":"product_tag-deficit-de-vitamina-b12","12":"product_tag-malabsorbtie","13":"product_tag-vem-crescut","14":"pa_conditii-medicale-afecti-anemii-feripriva-megaloblastica","15":"pa_conditii-medicale-afecti-boala-celiaca","16":"pa_conditii-medicale-afecti-boli-inflamatorii-intestinale-rectocolita-ulcerohemoragica-boala-crohn","17":"pa_conditii-medicale-afecti-gastrite-infectioase-autoimuna-ulcer","18":"pa_conditii-medicale-afecti-neuropatie-periferica","20":"first","21":"instock","22":"sale","23":"virtual","24":"purchasable","25":"product-type-simple"},"acf":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.clinica-sante.com\/ro\/wp-json\/wp\/v2\/product\/26539","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.clinica-sante.com\/ro\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.clinica-sante.com\/ro\/wp-json\/wp\/v2\/types\/product"}],"wp:attachment":[{"href":"https:\/\/www.clinica-sante.com\/ro\/wp-json\/wp\/v2\/media?parent=26539"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.clinica-sante.com\/ro\/wp-json\/wp\/v2\/product_brand?post=26539"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.clinica-sante.com\/ro\/wp-json\/wp\/v2\/product_cat?post=26539"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.clinica-sante.com\/ro\/wp-json\/wp\/v2\/product_tag?post=26539"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
