Salmonella enterica subsp enterica contains a large number of serovars accounting for more than 99.5% of isolated Salmonella strains. Among these serovars, S. enterica subsp. enterica serovar Typhi and S. enterica subsp.
Enterica serovar Paratyphi, often called as S. typhi and respectively for short, are of important clinical signifificance, since these two serovars are associated with typhoid fever and paratyphoid fever. Typhoid fever, also named typhoid, is a bacteria l infection due to S. typhi. Symptoms may vary from mild to severe and usually begin six to thirty days after exposure. For patients with typhoid, S. typhi, growing in the intestines and blood, can be transmitted by oral-fecal route. Paratyphoid, another type of enteric fever, is caused by A, B or C. Paratyphoid resembles typhoid in signs and symptoms.
The Salmonella Typhi Antigen Rapid Test is a rapid visual immunoassay for the qualitative presumptive detection and difffferentiation of S. typhi A antigens in human fecal specimens. This kit is intended to be used as an aid in the detection and difffferentiation of S. typhi A associated with typhoid fever or paratyphoid fever with a high degree of sensitivity and specifificity.
Positive: Two lines appear. One red line should be in the control region (C), and another apparent red or pink line adjacent should be in the test region (T).
Negative: Only one red band appears in the control region (C), and no band appears either in the T region.
Invalid: No red band appears in the control region (C), whether a test band(s) is present or not. Repeat invalid tests with a new sample, new test device and reagent. Insuffiffifficient sample volume, inaccurate operating procedure or expired tests may yield an invalid result. Contact your local distributor if the problem continues.
