A presença de hemólise na amostra é uma das principais fontes de invalidação do exame de Perfil Lipídico Hilab e talvez seja uma das principais fontes de erros laboratoriais.
Saiba como evitar esse problema.
A hemólise é a destruição prematura das hemácias por rompimento da membrana plasmática, que resulta na liberação de componentes intracelulares como a hemoglobina.
Para evitar a hemólise em uma amostra de punção digital, é essencial seguir algumas recomendações.
A primeira delas, está relacionada à assepsia do dedo do paciente. Após fazer a limpeza com o lenço de álcool, você deve esperar o álcool secar para então, perfurar o dedo do paciente com a lanceta.
O álcool residual no local da punção pode causar a hemólise na amostra. Pelo mesmo motivo, você não deve, em hipótese alguma, secar a primeira gota de sangue com o lenço de álcool.
A primeira gota de sangue deve ser limpa com um algodão ou gaze secos.
O garrote incorreto também resulta na hemólise da amostra. Por esse motivo, é muito importante fazer o garrote correto.
Para fazer esse garrote, faça um jóia com o polegar e posicione o dedo do paciente entre o seu dedo polegar e indicador, segurando em volta do dedo do paciente, na altura da primeira falange do dedo, por aproximadamente 10 segundos. Não ordenhe o dedo do paciente.
Fique atento às principais causas de hemólise, principalmente ao realizar o exame de Perfil Lipídico.
A hemólise pode impactar negativamente o atendimento ao paciente, uma vez que na maioria dos casos, o extravasamento das hemácias impede a liberação do laudo. Desta forma, você precisará repetir o exame.
