Summary
The VDRL + TPHA test combination is the most cost-effective method for diagnosing syphilis in pregnant patients. This approach ensures accurate syphilis detection while minimizing healthcare expenses.
Area of Science:
- Medical Laboratory Science
- Public Health
- Obstetrics and Gynecology
Background:
- Syphilis poses significant preventable risks to mothers, fetuses, and children.
- Early prenatal screening for syphilis is crucial.
- Current syphilis diagnosis relies heavily on serological tests like VDRL, RPR, FTA, and TPHA.
Purpose of the Study:
- To evaluate the cost utility of different serological test combinations for syphilis diagnosis in obstetrical practice.
- To identify the most economical and accurate diagnostic approach.
Main Methods:
- Analysis of four diagnostic algorithms: VDRL + FTA, VDRL + TPHA, RPR + FTA, and RPR + TPHA.
- Evaluation of cost per accurate diagnosis for each combination.
Main Results:
- The VDRL + TPHA combination demonstrated the lowest cost per accurate diagnosis.
- The RPR + FTA combination was identified as the most expensive option.
Conclusions:
- The VDRL + TPHA combination is the most economically advantageous method for serological syphilis diagnosis.
- This finding supports the application of medical laboratory economics principles in clinical practice.
