This oversensitivity can complicate crime scene analysis and potentially compromise the integrity of evidence.

Another challenge lies in the temporal limitations of luminol-based detection. The chemiluminescent reaction that makes luminol effective is also relatively short-lived, typically lasting only about 30 seconds. This brief window of visibility can make it difficult for investigators to thoroughly document and analyze larger crime scenes, potentially missing crucial evidence.

The environmental factors affecting luminol's performance pose additional challenges. Temperature, humidity, and the presence of other chemicals can all influence the reaction's intensity and duration. These variables can lead to inconsistent results across different crime scenes or even within the same location, making standardization and reliable interpretation of results more complex.

Furthermore, the equipment used in conjunction with luminol for high-sensitivity detection often struggles with quantification. While luminol can indicate the presence of blood, accurately determining the amount or age of the blood sample remains challenging. This limitation can hinder investigators' ability to reconstruct crime scenes or establish timelines accurately.

The potential for contamination during the application of luminol also presents a significant challenge. The very act of spraying luminol can potentially alter or destroy other forms of evidence, such as DNA or fingerprints. This risk necessitates careful consideration and sequencing of evidence collection procedures, which can be time-consuming and may not always be feasible in all investigative scenarios.

Lastly, the interpretation of luminol-enhanced evidence requires considerable expertise. The subtle variations in luminescence intensity and pattern can be difficult to interpret accurately, especially under the time constraints imposed by the reaction's short duration. This challenge underscores the need for highly trained personnel and potentially advanced imaging technologies to capture and analyze the luminol reactions effectively.

The luminol-based high-sensitivity detection equipment market is in a growth phase, driven by increasing demand for forensic and clinical applications.
