Abstract:
This study was conducted among blood donors in Central Blood Bank of
Khartoum. On a total of ninety tow samples were collected, during the period from
March to May 2018, to demonstrate the frequency of syphilis and to compare
between different diagnostic methods for detection of syphilis. All samples were
tested from ELISA, ICT and RPR. The seroprevalence of syphilis revealed from
ELISA method was 7(7.6 %), which was equal to ICT but was slightly increase in
RPR 8 (8.7%). The high frequency of syphilis 3 (42.9%) was found in both age
group of (26-35and36-45). There was no positive cases between the ages of (46-
55) years. 5 (71.4%) of positive samples were seen among single blood donors, 2
(28.6%) among married donors and no positive cases among divorced blood
donors. ICT method showed 100% sensitivity and 100% specificity. RPR showed
100% sensitivity and 98.8% specificity. Results showed that the ICT used in this
study was the same when compared with ELISA but the RPR showed less
specificity than ELISA .
The study concluded that ICT with ELISA were the best methods for screening
blood donors.
