Para ajud\u00e1-lo a tomar essa decis\u00e3o para sua fam\u00edlia, aqui est\u00e3o alguns motivos pelos quais os pais geralmente optam por fazer o teste:&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-confidence-in-chromosomal-normalcy\">Confian\u00e7a na normalidade cromoss\u00f4mica<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Ao rastrear os embri\u00f5es quanto a anormalidades gen\u00e9ticas antes da implanta\u00e7\u00e3o, o PGT permite que os pais selecionem apenas os embri\u00f5es livres de anormalidades cromoss\u00f4micas, aumentando a confian\u00e7a na sa\u00fade e na qualidade de vida de seu futuro filho.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-decreased-miscarriage-rates\">Diminui\u00e7\u00e3o das taxas de aborto<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Como foi demonstrado que aumenta significativamente as taxas de nascidos vivos, muitos pais escolhem o PGT para melhorar suas chances de sucesso, mesmo que n\u00e3o tenham hist\u00f3rico pessoal ou familiar de aborto espont\u00e2neo ou natimorto.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-reduced-risk-of-genetic-disease\">Risco reduzido de doen\u00e7as gen\u00e9ticas<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">A triagem do portador permite que os pais entendam seu risco pessoal para dist\u00farbios gen\u00e9ticos suspeitos, e o PGT permite que os pais que identificaram um alto risco tomem medidas para prevenir uma gravidez afetada. Com o PGT-M, nossos m\u00e9dicos do ICRM ajudaram muitos casais a voltar para casa com um beb\u00ea saud\u00e1vel - mesmo quando ambos os pais eram portadores da mesma doen\u00e7a gen\u00e9tica.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-improved-efficiency-lower-cost\">Maior efici\u00eancia e menor custo<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Uma das raz\u00f5es pelas quais muitos pais optam por se submeter ao PGT \u00e9 melhorar a efici\u00eancia do processo de fertiliza\u00e7\u00e3o in vitro. Ao selecionar apenas os embri\u00f5es livres de certas condi\u00e7\u00f5es gen\u00e9ticas, o PGT pode aumentar as chances de uma gravidez bem-sucedida e ajudar a evitar a necessidade de v\u00e1rias rodadas de fertiliza\u00e7\u00e3o in vitro. Isso n\u00e3o apenas pode economizar tempo e dinheiro para os pais, mas tamb\u00e9m o custo emocional de tentativas fracassadas de fertiliza\u00e7\u00e3o in vitro.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-can-i-expect-of-pre-genetic-testing\">O que posso esperar dos testes pr\u00e9-gen\u00e9ticos?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">As triagens de portadores s\u00e3o r\u00e1pidas e simples, exigindo um exame de sangue ou uma amostra de saliva. No ICRM, normalmente coletamos amostras de sangue, embora nossos pacientes de fora da cidade tenham a op\u00e7\u00e3o de coletar sua pr\u00f3pria amostra com um kit de coleta de saliva em casa. Uma vez coletadas, as amostras de DNA s\u00e3o enviadas para um laborat\u00f3rio onde s\u00e3o triadas para todos os dist\u00farbios solicitados pelo paciente.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">O PGT envolve uma bi\u00f3psia dos embri\u00f5es em seu est\u00e1gio de blastocisto: 5 a 10 c\u00e9lulas s\u00e3o coletadas das c\u00e9lulas do trofectoderma - essas s\u00e3o c\u00e9lulas que se tornam a placenta, n\u00e3o o feto.
