Comprehensive 14-Pathogen STI Detection Solution for Accurate Molecular Diagnosis

Sexually transmitted infections (STIs) continue to pose a serious global public health challenge due to their high prevalence, diverse pathogen spectrum, and frequently asymptomatic nature. If left undiagnosed or untreated, STIs can lead to severe complications such as infertility, ectopic pregnancy, chronic pelvic inflammation, neonatal infections, and even increased cancer risk. Early, accurate, and comprehensive detection is therefore essential for effective clinical management and disease control.

The Kit de detectare a infecțiilor cu transmitere sexuală Cowingene 14 tipuri (lichid) is an advanced in vitro diagnostic (IVD) solution designed to provide rapid and reliable qualitative detection of 14 clinically significant STI pathogens. Utilizing multiplex real-time PCR technology, the kit enables simultaneous identification of multiple infectious agents in a single workflow, significantly improving diagnostic efficiency and clinical decision-making.

Intended Use: Broad-Spectrum Detection Supporting Clinical Diagnosis

This detection kit is specifically intended for the qualitative detection of the following pathogens associated with genitourinary tract infections:

Chlamydia trachomatis (CT) 

Neisseria gonorrhoeae (NG) 

Mycoplasma hominis (Mh) 

Mycoplasma genitalium (Mg) 

Ureaplasma urealyticum (UU) 

Ureaplasma parvum (UP) 

Herpes simplex virus type 1 (HSV1) 

Herpes simplex virus type 2 (HSV2) 

Candida albicans (CA) 

Gardnerella vaginalis (GV) 

Trichomonas vaginalis (TV) 

Streptococul de grup B (GBS) 

Haemophilus ducreyi (HD) 

Treponema pallidum (TP) 

The results obtained from this kit serve as important auxiliary evidence for clinicians in the diagnosis and treatment of STIs and related infections. It is suitable for use in hospitals, diagnostic laboratories, and sexual health screening centers, supporting both routine testing and large-scale screening programs.

Flexible Sample Types: Designed for Diverse Clinical Scenarios

To accommodate real-world clinical needs, the kit supports multiple specimen types, including:

Urine samples

Male urethral swabs

Female cervical swabs

Female vaginal swabs

This flexibility allows healthcare providers to select the most appropriate sampling method based on patient condition and testing requirements. The compatibility with self-collected and clinician-collected samples also enhances patient compliance and facilitates broader screening coverage.

Performance Characteristics: High Sensitivity, Specificity, and Stability

High Sensitivity for Early Detection

The kit demonstrates a limit of detection (LoD) of 400 copies/mL across all 14 targets. This high sensitivity ensures reliable detection even in low pathogen load conditions, making it particularly valuable for early-stage infections and asymptomatic carriers.

Excellent Specificity and No Cross-Reactivity

Extensive validation confirms that the kit shows no cross-reactivity with a wide range of non-target microorganisms and nucleic acids, including:

High-risk HPV (16/18)

Escherichia coli 

Staphylococcus epidermidis şi Staphylococcus saprophyticus 

Lactobacillus species

Adenovirus, Cytomegalovirus (CMV), HIV

Human genomic DNA

This ensures highly accurate pathogen identification and minimizes false-positive results.

Strong Resistance to Interference

The assay maintains stable performance in the presence of common interfering substances such as:

Blood, semen, cervical mucus

White blood cells and mucin

Antibiotics (e.g., levofloxacin, azithromycin, erythromycin, penicillin)

Vaginal care solutions

This robustness reflects real clinical sample conditions and enhances test reliability.

High Precision and Reproducibility

The kit demonstrates excellent repeatability and reproducibility, with coefficient of variation (CV) ≤ 5%, ensuring consistent performance across different runs, operators, and laboratory environments.

Advanced Technical Specifications for Modern Molecular Laboratories

Detection Method: Multiplex real-time PCR (4-tube system)

Detection Channels: FAM, VIC/HEX, ROX, CY5
