Since the 1970s in Korea, consistent with the global trend, there has been a fast decrease in positive rates for syphilis. In 2000, 0.2% of the general Korean population was estimated to be syphilis-positive; since that time, degrees appear to have decreased, and the prevalence rate is still very low. 1 Despite these low rates, syphilis is an important infection since it can cause serious health problems including neurosyphilis and congenital infection. Proper confirmation, screening and follow-up protocols are required. Std Test in Lake Forest, IL, United States. 2-4 Serological investigation of non-treponemal reagin tests, like the Venereal Disease Research Laboratory (VDRL), rapid plasma reagin (RPR) and treponemal tests like the Treponema pallidum haemagglutination assay (TPHA), the Treponema pallidum particle agglutination (TPPA) test, the fluorescent treponemal antibody absorption test, along with the Treponema-specific antibody evaluation, have been used to diagnose and monitor syphilis diseases. Lately, there have been problems regarding choice of the finest algorithm for first screening and follow-up by either non-treponemal- or treponemal-specific tests. 2 5 6 The Centers for Disease Control and Prevention (CDC) still urge that a non-treponemal reagin test is used as the first-line diagnostic strategy. 2 Two types of non-treponemal test have been widely used: RPR and VDRL. RPR is the most common first-line non-treponemal test used to screen for syphilis disease. Lake Forest Illinois std test. 7 Recently, automated RPR tests have been introduced, but changeable results were reported when the automated test was compared with standard RPR card tests. 8 The automated RPR test has some advantages over the standard RPR card test, including greater ability to deal with a high number of samples, minimal person-to-person variation, and simple automated processes.

All sera testing positive for syphilis by one or more tests from November 2012 from a university hospital to April 2013 were included, together with matched controls. Remnant sera from requested treponemal tests after proof were included and maintained at 70C until investigation. Patients weren't categorised according to syphilis stage because of the infrequency of syphilis infection. Instances of accurate syphilis were quite rare because of the low prevalence of syphilis in this nation. The goal of the study was to assess the same RPR tests with remnant specimens that are protected that are ethically. The institutional review board exempted this case. All study processes complied with the World Medical Association Declaration of Helsinki.

HiSens Auto RPR LTIA (HBI, Anyang, Korea) is a latex turbidimetric immunoassay using latex particles coated with lecithin and cardiolipin. The latex particles react with the reagin in the serum of patients with syphilis. The 15 L serum samples were allowed to react with 120 L Hisens automobile RPR LTIA R1 (buffer) and 60 L Hisens auto RPR LTIA R2 (latex reagent comprising cardiolipin-lecithin-cholesterol, 1.0 mg/mL) in a CA-400 autoanalyzer (Furuno Electric Co, Nishinomiya, Japan). The CA400 photometric analyser was utilized for the automated procedure and evaluation. Absorbance at 600 nm was read after 5.3 and 10 s at room temperature, in duplicate. Results of the HiSens automobile RPR test equal to or greater than 1.0 RPR unit (RU) were considered to indicate reactive RPR. The top detection limit was 20 RU.

The Serodia TPPA assay (Fujirebio, Tokyo, Japan) is based on agglutination of coloured gelatine particles that have been sensitised (coated) with T. pallidum (Nichols strain) antigen. For every specimen, a 100 L sample of diluent and 25 L test specimen were blended, and twofold serial dilutions were made with 25 L sample diluent. The particles that are sensitised were serially combined in the neighbouring wells using a plate mixer for 30 s. After 2 h of incubation at room temperature, the consequence of the agglutination assay was read. The Serodia TPPA assay results were interpreted utilizing the agglutination patterns of negative and positive controls.

The percent agreement ( coefcient) of the automated RPR test with the manual RPR card test was calculated. The overall sensitivity and specificity of every test were computed based on the TPPA results. values were used to categorise results as quite good (0.81-1.0), great (0.61-0.8), average (0.41-0.6), reasonable (0.21-0.4) or poor (0-0.2). Std test near Lake Forest IL. 9 The McNemar test was used to compare seroconversion rates between the automated RPR test and the conventional manual RPR card test and was performed using SPSS Statistics V.20. A p value

There were 24 discrepant results (21.4%) between the two RPR evaluations, including 22 negative HBI HiSens Auto RPR LTIA test results that demonstrated positive results on the BD Macro-Vue RPR card test. Of these 22 discrepant results, 20 were TPPA positive and 2 were TPPA-negative, while 2 cases were favorable on the HBI HiSens Auto RPR LTIA test but negative on the BD Macro-Vue RPR card test. These two instances were negative on the TPPA test. Lake Forest Std Test. There were four results with disparities between both the RPR tests and the TPPA assay, which was due to conditions apart from syphilis infection ( table 2 ). The power of agreement between the automated RPR and manual RPR tests was 'fair' ( worth 0.296, 59 TPPA-positive results; value 0.293, 53 TPPA-negative results) according to the TPPA results ( table 3 ).

Std test nearest Lake Forest Illinois. The overall sensitivity and specificity of the HBI HiSens Auto RPR LTIA test based on TPPA results were 52.5% (95% CI 39.1% to 65.7%) and 94.3% (95% CI 84.3% to 98.8%), respectively. The overall sensitivity and specificity of the BD Macro-Vue RPR card test were 86.4% (95% CI 75% to 93.9%) and 94.3% (95% CI 84.3% to 98.8%), respectively ( table 4 ). Automated RPR gave a higher seroconversion rate after syphilis treatment (43.5% (10/23)) than the normal RPR card test (4.3% (1/23)) (p=0.004) by the McNemar test. A detailed comparison of the treated syphilis cases is given in table 5

An automated RPR test was established and has been used because of its convenience in clinical settings, but although the manual RPR test has been used for decades. Yet, there was a need for thorough review as well as a comparison of results of this new automated evaluation together with the standard manual RPR test in diagnostic strategies. Treponemal test results will not change even after treatment, and also the patients live no matter treatment or disease activity with favorable results for the rest of their lives. Treponemal tests cannot discriminate between previous infections, aggressive disease, treated patients and non -treated patients. 10 In contrast, non-treponemal tests can discriminate between patients who've been treated during the primary or secondary stage of the illness. When the primary or secondary phase of a first T. pallidum infection is treated, the non-treponemal test titre should show a twofold dilution fall after treatment, usually within 6 months. Std Test nearby IL. 7 Therefore, the non-treponemal test is essential for managing syphilitic patients.

In our study, the standard BD Macro-Vue RPR card test showed better sensitivity in relation to the HBI HiSens Auto RPR LTIA evaluation in syphilis screening, although the automated RPR test does have some advantages in the clinical setting. For instance, the automated RPR test reduced the workload and overall test turnaround time. It doesn't need test experts and can also deal with greater test amounts in a specified time than the manual RPR card test. Also, we detected the automated RPR test could be used as a tracking marker of treatment response, particularly if treponemal tests are used for first-line screening of syphilis as a reverse algorithm of syphilis testing. This reverse algorithm for syphilis testing was proposed and adopted in many areas as it might be powerful and more sensitive in relation to the standard algorithm 3 4 6 in a low-prevalence area and can be automated. On the other hand, the CDC still advocate first screening for syphilis with a non-treponemal test such as RPR. 2

Our study found that the automated RPR test revealed earlier seroconversion in relation to the traditional card RPR test after syphilis treatment (p=0.004). If we adopt the inverse algorithm, treponemal tests can be used to screen sensitively, and then non-treponemal tests could be used to correctly reveal negative changes in treated cases. In this situation, we could use treponemal tests for first-line screening and non-treponemal tests for monitoring patients allowing us to observe seroconversion more efficiently after treatment. 2 13 14 Regrettably, our study had a limited number of syphilitic patients due to the low prevalence of syphilis in our nation, or so the variety of samples was small and could not been classified according to syphilis stage. In fact, in some late or latent syphilis cases, the results of the non-treponemal test were difficult to interpret after first treatment in our study (cases 8 and 9 in table 5 ). So, further well-designed studies are needed to clarify the serological responses of automated RPR tests after treatment and as stated by the point of syphilis disease.

In Korea, automated RPR tests have recently been introduced in clinical laboratories, and evaluations comparing VDRL tests and standard RPR tests are reported. 8 15 Nevertheless, the results were varying. Onoe et al 16 also proposed that, when the automated serological testing procedure is utilized in clinical settings, the exact same reagent ought to be consistently chosen to evaluate the changes in antibody titres, since the manual serological testing way of syphilis showed somewhat different effects from the automated serological testing procedures. In this study, we noticed relatively consistent results between automated and manual RPR tests.

In conclusion, an entire lower sensitivity and similar specificity was shown by the automated RPR test compared with the traditional manual RPR card test. Thus, we consider the automated RPR test is not suitable for use for first screening for syphilis. However, it generates an earlier seroconversion reaction in treated cases in relation to the standard RPR card test. Using the inverse algorithm, the sensitive treponemal test can be utilized as the first-line screening test, and the automated RPR test can be put to use as an adjunct to detect earlier seroconversion in patients that were treated.

Results The percent deal between the two RPR evaluations was 78.6% ( 0.565; 95% CI 0.422 to 0.709). Sensitivity and specificity of the automated RPR test relative to the TPPA evaluation was 52.5% (95% CI 39.1% to 65.7%) and 94.3% (95% CI 84.3% to 98.8%), respectively, while the same values for the normal RPR card test were 86.4% (95% CI 75% to 93.9%) and 94.3% (95% CI 84.3% to 98.8%), respectively. The normal RPR card test showed overall higher positivity than the automated RPR test, while the automated RPR test demonstrated higher seroconversion (43.5%, 10/23) than the normal RPR card test (4.3%, 1/23) in treated patients.
