A recently granted patent (Publication Number: US11994524B2) discloses a stool resuspension solution designed to stabilize hemoglobin effectively. The solution includes protoporphyrin complexed with Cr3+ or Co3+, with specific concentrations outlined for optimal stabilization. Protoporphyrin IX is identified as the protoporphyrin used in the solution, which is crucial for maintaining hemoglobin stability. Additionally, the solution's pH range is specified to be between pH 6.5 to pH 7.4, ensuring the ideal environment for its intended purpose.
Moreover, the patent also covers a stool sample collection device that incorporates the stool resuspension solution. This device features a stool sample collection container with an open end and a stool resuspension solution containing the specified protoporphyrin complexes to stabilize hemoglobin effectively. The device includes a stool sampling rod with a beveled tip for collecting stool samples, ensuring a secure connection to the sample collection container. The concentrations of protoporphyrin complexes, pH range, and the use of protoporphyrin IX are consistent with those outlined for the stool resuspension solution, emphasizing the importance of these factors in the collection process. The device's design and components aim to streamline the stool sample collection process while maintaining the integrity of the samples for subsequent analysis.
