Accurate and Reliable HSV-1/2 Molecular Detection for Clinical Diagnosis

Herpes Simplex Virus (HSV) infection is one of the most prevalent viral infections worldwide and remains a significant concern in the field of sexually transmitted infections (STIs). Due to its lifelong persistence, potential for recurrence, and often asymptomatic presentation, HSV poses a continuous challenge for clinical diagnosis and infection control. Without timely detection and proper management, HSV infections may lead to complications such as neonatal transmission, increased susceptibility to other infections, and serious reproductive health issues.

The Kit de detectare a virusului Herpes Simplex Cowingene 1/2 (liofilizat) is an advanced in vitro diagnostic (IVD) solution designed for the qualitative detection of HSV-1 and HSV-2. Based on real-time PCR technology, this kit enables rapid, sensitive, and specific identification of viral DNA, providing reliable support for clinical diagnosis and treatment of genitourinary tract infections.

Intended Use: Targeted HSV Detection for Clinical Decision Support

This detection kit is specifically intended for the qualitative detection of Herpes Simplex Virus type 1 (HSV-1) and type 2 (HSV-2) in human clinical samples. It provides important auxiliary information for clinicians in diagnosing HSV-related infections and guiding therapeutic strategies.

HSV is primarily transmitted through close contact:

HSV-1 is commonly spread via oral contact and causes oral herpes (cold sores), but can also lead to genital infections

HSV-2 is mainly transmitted through sexual contact and is the leading cause of genital herpes

Given the overlapping clinical symptoms and differences in transmission patterns, accurate differentiation between HSV-1 and HSV-2 is critical for effective patient management and epidemiological control.

Flexible Sample Types: Adapted to Real Clinical Needs

The kit is validated for use with multiple clinically relevant specimen types:

Urine samples

Male urethral swabs

Female cervical swabs

Female vaginal swabs

This multi-sample compatibility allows healthcare providers to choose appropriate collection methods based on patient conditions, improving diagnostic flexibility and patient compliance. It is suitable for both clinician-collected and self-collected samples, supporting broader screening applications.

Performance Characteristics: High Sensitivity and Diagnostic Accuracy

High Sensitivity for Early Detection

The kit achieves a limit of detection (LoD) of 400 copies/mL, ensuring reliable detection of HSV DNA even at low viral loads. This is particularly important for early-stage infections and asymptomatic carriers, where viral concentration may be minimal.

Accurate Differentiation of HSV-1 and HSV-2

Using multiplex real-time PCR technology, the kit enables simultaneous detection and differentiation of HSV-1 and HSV-2 within a single reaction tube. This improves diagnostic efficiency and reduces testing time.

Reliable and Reproducible Results

The PCR-based detection system ensures high specificity and minimizes false-positive or false-negative results. It provides stable and consistent performance across different laboratory conditions.
