Our Testing Services
Devansh Labs has developed a qPCR based test with a resistance option for rapid detection, speciation, and resistance profiling of wound pathogens. Submit a swab that has been gently wiped over the infected region of skin to our lab and we will perform the DNA extraction and qPCR analysis of the listed pathogens commonly seen in wound infections with immediate reporting.
Accurate and prompt identification and determination of wound pathogens is key to proper wound management for patients suffering from pathogenic infection. The majority of skin wounds are colonized with both aerobic and anaerobic bacteria and yeast.
Because efficiency and turnaround time are so important to physicians and their patients, Devansh Labs uses quantitative polymerase chain reaction (qPCR or Real-Time PCR) which is faster than traditional PCR.

FAQ's
The Wound Pathogens Panel (WPP) is a molecular diagnostic test designed to detect bacterial and fungal infections in wounds. DLW’s WPP utilizes qPCR technology to accurately identify a wide range of pathogens, enabling targeted treatment decisions.
Chronic and acute wounds often involve polymicrobial infections, making it difficult to pinpoint the exact pathogens. WPP testing helps:
→ Accurately detect bacterial and fungal infections.
→ Guide targeted antibiotic and antifungal treatment
→ Reduce complications and promote faster healing
DLW’s comprehensive WPP panel detects:
→ Gram-positive bacteria: Staphylococcus aureus, Enterococcus spp., Streptococcus spp.
→ Gram-negative bacteria: Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae
→ Anaerobes: Bacteroides spp., Clostridium spp.
→ Fungal species: Candida albicans, Candida glabrata
This broad detection range helps in identifying mixed infections and tailoring effective treatments.
A swab or tissue sample is collected directly from the wound site and sent to DLW’s laboratory for analysis. The sample undergoes:
→ DNA extraction
→ qPCR analysis for rapid and accurate pathogen identification
WPP testing provides pathogen-specific results, allowing healthcare providers to:
→ Prescribe the most effective antibiotics or antifungal medications
→ Reduce antibiotic resistance risks
→ Promote faster wound healing and prevent recurrence
Yes, DLW’s WPP panel can identify critical antibiotic resistance genes, including:
→ mecA – Methicillin resistance
→ vanA – Vancomycin resistance
→ blaKPC, blaOXA-48 – Carbapenem resistance
This ensures personalized and effective treatment plans for better infection management.
DLW’s WPP is suitable for diagnosing infections in:
→ Diabetic foot ulcers
→ Pressure sores
→ Surgical site infections
→ Traumatic wounds
→ Chronic non-healing wounds
Testing these wounds helps improve wound care strategies and prevent complications.
Chronic wounds often contain biofilms and multiple pathogens that delay healing. WPP testing helps by:
→ Identifying the exact microbial composition
→ Guiding precise antimicrobial treatment
→ Accelerating wound closure and reducing infection recurrence
DLW’s qPCR-based WPP provides higher sensitivity and specificity than traditional culture methods. While cultures may miss anaerobic or slow-growing organisms, WPP accurately detects a broad range of pathogens, ensuring reliable and faster results.
DLW’s advanced molecular diagnostics enable a rapid turnaround time, ensuring clinicians receive timely results for prompt and effective treatment decisions.
