A Rapid Screening Test for Lactic Aciduria

A rapid screening test for pleural exudates.

Measurement of 4-hydroxyphenylacetic aciduria as a screening test for small-bowel disease.

We evaluted measurement of urinary 4-hydroxyphenyl acetic acid as a potential screening method for small-bowel disease and bacterial overgrowth syndromes in 360 unselected acutely ill infants and children. Control data were obtained on 120 healthy children, ages 1.5 to 15 years, from a general medical practice, 48 healthy infants, ages one to five years, from local day nurseries, and 150 health...

Evaluation of a new rapid plasma reagin card test as a screening test for syphilis.

This study evaluates the American Dade (Biokit Laboratories) rapid plasma reagin (Dade RPR) card test, currently used in Spain for the diagnosis of syphilis, which has been recently released to the U.S. market. Used as a basis for comparison with the Dade card test were the 18-mm standard rapid plasma reagin (standard RPR) card test and the Venereal Disease Research Laboratory (VDRL) slide test...

Rapid screening test for enterotoxin-producing Bacillus cereus.

Culture supernatants of 30 enterotoxin-producing Bacillus cereus isolates produced a characteristic progressive destruction of McCoy cell monolayers. Enterotoxin-negative B. cereus and other group 1 Bacillus spp. caused no monolayer disruption. The McCoy cell tissue culture system appears to provide a rapid screening assay for detection of enterotoxin-producing B. cereus.

Rapid screening test for the diagnosis of rotavirus infection.

The early diagnosis of human rotavirus infection is essential for effective patient management and infection control. We report here a rapid, easy-to-perform, and inexpensive test for rotavirus detection. The viral RNA is extracted directly from the stools and electrophoresed on 1% agarose gels. Currently available immunoassays for routine diagnostic purposes are directed at the common group A-...
