EN LA PRESENTE INVENCION SE PRESENTAN NUEVOS CARTUCHOS DE ENSAYO A UTILIZAR EN EL ENSAYO DE MUESTRAS LIQUIDAS Y METODOS PARA LLEVAR A CABO TALES ENSAYOS. The present invention provides novel test cartridges for use in the assay of liquid samples and methods of carrying out such assays. These test cartridges are particularly useful in assays which include at least one step during which the sample to be assayed and one or more components of the assay system are kept separated by a pierceable member. The test cartridges comprise a housing through which the sample flows during the assay. The housing includes a holding chamber for holding the sample and a test chamber separated by a pierceable member. The test chamber further includes a partition member which has an opening therethrough and includes at least one reagent for the assay. A transfer member movably mounted in the test chamber can move towards and pierce the pierceable member and contact the liquid sample in the holding chamber. When the transfer member has been moved towards and pierces the pierceable member to contact the liquid sample and a negative pressure is created in the test chamber, liquid sample moves through the transfer member, into the test chamber and through the opening in the partition member.
