Overview
AI-generated summary, 19 Sep 2026
The Alkaline Phosphatase Assay Kit is an in vitro diagnostic device designed to measure alkaline phosphatase (ALP) activity in biological samples. It utilises p-nitrophenyl phosphate, which is hydrolysed by ALP into a yellow-coloured product, enabling quantitative assessment of enzyme activity via absorbance at 405 nm. This assay aids in the evaluation of ALP or its isoenzymes for diagnostic purposes, particularly in assessing liver, bone, parathyroid, or intestinal conditions.
The kit is supplied as a single-use reagent system for laboratory use, requiring no sample pretreatment. It is intended for use in clinical chemistry settings and has received FDA 510(k) clearance under the classification of Class II (CJE). No third-party review or reprocessing is permitted, and storage conditions are not specified in the regulatory data. The device is authorised under regulation number 862.1050 and is associated with multiple registration numbers for compliance tracking.

Questions
AI-generated answers, 19 Sep 2026
What clinical conditions can this assay help evaluate when measuring alkaline phosphatase levels?
This assay is designed to measure alkaline phosphatase (ALP) activity, which aids in evaluating liver, bone, parathyroid, or intestinal conditions. By quantifying ALP or its isoenzymes through absorbance at 405 nm, clinicians can assess potential abnormalities linked to these systems, such as bone metabolism disorders, liver disease, or parathyroid dysfunction.
Is this kit reusable, or is it intended for single-use only?
The kit is explicitly labeled as a single-use reagent system, meaning it cannot be reused or reprocessed after one use. This design ensures accuracy and safety in laboratory settings, as third-party reprocessing is not permitted.
What type of biological samples can be tested with this assay, and does it require any sample pretreatment?
The kit is intended for use with biological samples in clinical chemistry settings, but it does not require any sample pretreatment. This simplifies workflows by allowing direct measurement of ALP activity without additional preparation steps.
How is this device regulated, and what does the FDA clearance classification mean for its use?
The kit received FDA 510(k) clearance under the classification of Class II (CJE), meaning it is considered a moderate-risk device. This classification ensures it meets stringent regulatory standards for safety and effectiveness in measuring ALP activity, while also requiring compliance with specific manufacturing and labeling requirements.
Are there any specific storage instructions provided for this assay kit?
The regulatory data does not specify storage conditions for this kit, so it is important to refer to the manufacturer’s instructions for proper handling. Typically, such assays should be stored according to guidelines for reagent stability, such as refrigeration or room temperature, but exact details would be provided by Diagnostic Chemicals, Ltd.
