<p>A screening method for the determination of 10⁴ gram negative bacteria per milliliter of an undiluted urine sample and a unitary screening test device for the determination of at least 10⁵ gram negative bacteria per milliliter of an undiluted urine sample. The method and test device make use of Limulus amebocyte lysate (LAL) and a synthetic substrate containing a chromogenic or fluorogenic leaving group capable of being cleaved by activated lysate. This screening method and unitary screening device provide a quick, convenient, inexpensive indication of the possible presence of a urinary tract infection caused by gram negative bacteria. </p> |
