Description
VDRL Antigen with 60 mL Buffered Saline for Syphilis Serology, 5 mL (BD)
The BD VDRL Antigen with Buffered Saline is an in vitro diagnostic reagent set designed for use in non-treponemal serologic testing for syphilis using the VDRL (Venereal Disease Research Laboratory) slide flocculation method. This product provides a standardized VDRL antigen suspension supplied with buffered saline to support proper reagent preparation and test performance in clinical laboratories, public health settings, and other facilities performing syphilis serology.
Non-treponemal VDRL testing is commonly used as a screening and disease activity monitoring tool. Results may be reported qualitatively (reactive/nonreactive) and, when performed with serial dilutions, semi-quantitatively as a titer. As with all non-treponemal tests, VDRL results should be interpreted in conjunction with clinical findings, patient history, and confirmatory treponemal testing according to local algorithms and regulatory guidance.
Key Features
- Standardized VDRL antigen intended for slide flocculation testing under validated laboratory procedures.
- Buffered saline included to support appropriate preparation and handling consistent with method requirements.
- Designed for syphilis serology workflows where VDRL testing is used for screening and for monitoring response to therapy by titer changes.
- Suitable for laboratory use by trained personnel following institutional protocols and quality systems.
Product Configuration
| Component | Supplied Quantity | Purpose |
|---|---|---|
| VDRL Antigen | 5 mL | Primary reagent used to detect non-treponemal antibodies by flocculation. |
| Buffered Saline | 60 mL | Diluent/support reagent for preparation and performance consistent with the VDRL method. |
Intended Use and Applications
This reagent set is intended for professional use in performing the VDRL slide test on appropriate human specimens as defined by the test method and the laboratory’s validated procedures. Typical applications include:
- Serologic screening for syphilis as part of routine or targeted testing programs.
- Baseline non-treponemal titer determination prior to treatment.
- Follow-up testing to assess changes in titer over time, which may assist in monitoring disease activity and treatment response.
Handling, Storage, and Quality Practices
For best performance, store and handle reagents according to the manufacturer’s instructions for use (IFU). Laboratories should run appropriate internal and external quality controls, follow specified timing and mixing requirements, and ensure that equipment (such as rotators and pipettes) is calibrated and maintained. Do not use reagents beyond their expiration date, and do not interchange components with different lots unless permitted by the IFU.
Important Limitations
- VDRL is a non-treponemal test and is not specific for Treponema pallidum; reactive results require clinical correlation and confirmatory treponemal testing.
- Biological false positives can occur in certain medical conditions; titers must be interpreted in context.
- Improper technique, contamination, or incorrect environmental conditions may affect results; follow validated procedures and the IFU.
BD VDRL Antigen with Buffered Saline offers a convenient, laboratory-oriented reagent set to support standardized VDRL syphilis serology testing within established diagnostic workflows.
