The device description and performance studies focus on a chemical assay for measuring alkaline phosphatase activity, with no mention of AI or ML technologies.
No.
This device is an in vitro diagnostic reagent used for quantitative determination of Alkaline Phosphatase, which aids in diagnosis and treatment, but does not directly treat a disease.
Yes
The "Intended Use / Indications for Use" section explicitly states that "Measurements of Alkaline Phosphatase or its isoenzymes are used as in the diagnosis and treatment of liver, bone, parathyroid and intestinal diseases," which clearly indicates a diagnostic purpose.
No
The device is a reagent for in vitro diagnostic testing, which is a chemical substance used in a laboratory setting, not a software-only medical device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states that the reagent is intended for the "in vitro quantitative determination of Alkaline Phosphatase in human serum and plasma." The term "in vitro" means "in glass" or "outside the body," which is a key characteristic of IVDs.
- Purpose: The intended use also states that the measurements are "used as in the diagnosis and treatment of liver, bone, parathyroid and intestinal diseases." This indicates that the results obtained from this reagent are used for medical purposes related to diagnosis and treatment, which is the core function of an IVD.
- Device Description: The "Device Description" further clarifies that the reagents are for "in vitro quantitative determination" and describes the chemical reaction that occurs outside the body to measure the analyte.
- Performance Studies: The inclusion of performance studies like Method Comparison, Precision, Sensitivity, Reportable Range, and Specificity are standard requirements for demonstrating the analytical performance of an IVD.
Therefore, based on the provided information, this device clearly fits the definition of an In Vitro Diagnostic.

Device Description
The TRACE ALP - AMP (IFCC) method is based on the recommendations of the International Federation of Clinical Chemistry (IFCC) . This method utilizes 4-nitrophenylphosphate (4-NPP) as the substrate. Under the optimized conditions ALP present in the sample catalyses the following transphosphorylation reaction. At the pH of the reaction 4-NPP has an intense yellow color. The reagent also At the ph of the redeced i system to ensure that optimal concentrations of concurns a mood as a re maintained. The metal ion buffer can also chelate other potentially inhibitory ions, which may be present. The reaction is other potentially innibilory active in absorbance at 405 nm, which is proportional to the activity of ALP in the serum.

Description and Intended Use: TRACE Scientifics' alkaline phosphatase reagents are intended for the in vitro quantitative determination of alkaline phosphatase in human serum and plasma.
Clinical Significance ¹ :
Human alkaline Phosphatase (ALP) consists of a group of enzymes (at least five) which hydrolyze phosphates at an alkaline pH (6-8). ALP is found in practically all tissues of the body but in high concentrations in the osteoblasts of bone, liver, placenta, kidney, intestinal wall and lactating mammary glands. In adults, the ALP normally found circulating in the serum is largely derived from the liver. In children or in adolescents going through pubertal growth spurts there is an additional contribution from bone and this accounts for the higher reference interval for these groups. Pregnancy also raises the normal values of ALP.
Increased ALP (usually normal GGT) is seen in Osteomalacia and Rickets, primary hyperparathyroidism with bone involvement, Pagets disease, secondary carcinoma in bone and some cases of osteogenic sarcoma. Increased levels of ALP (usually with a raised GGT) is seen in cholestasis, hepatitis, cirrhosis, space occupying lesions and malignancy with bone or liver involvement or direct production. Low levels of ALP may be observed in conditions which cause arrested bone growth or in hypophosphatasia.
