Quest AD-Detect® Beta-Amyloid 42/40 Ratio, Plasma

 $320.49

This LC-MS/MS assay measures beta-amyloid 40 (AB40) as well as AB42 in plasma, rather than AB42 alone. This permits the normalization of beta amyloid levels circulating in plasma in different patients. Using the ratio of beta-amyloid 42/beta-amyloid 40, improves sensitivity and specificity for detecting Alzheimer's disease.

Quest AD-Detect® Phosphorylated tau217 (p-tau217), Plasma

 $320.49

Current research indicates that plasma p-tau, including p-tau 217, is concordant with amyloid status defined by either CSF biomarker testing or PET scan analysis, and is able to differentiate between AD and non-AD neurodegenerative diseases and to predict progression to AD. Blood-based biomarkers, such as plasma p-tau, could potentially be used as inclusion criteria or to evaluate target engagement and treatment efficacy, and could further advance the development of disease-modifying treatments in the field of AD and related disorders. This assay is designed specifically for the quantitative measurement of tau phosphorylated at threonine 217 (p-tau 217) in human plasma.

QuestAssureD 25-Hydroxy and Calcitriol 1,25-Dihydroxyvitamin D

 $63.49

Vitamin D originating from dietary and endogenous sources is converted to 25-hydroxyvitamin D in the liver, and subsequently to 1, 25-dihydroxyvitamin D in the kidney. Measurement of both the 1, 25-Dihydroxy and 25-Hydroxy forms provide insights into a variety of medical conditions such Vitamin D status in renal failure, differential diagnosis of primary, secondary and tertiary hyperparathyroidism. Differential diagnosis of hypercalcemia and type I and II inherited rickets.

QuestAssureD™ 25-Hydroxyvitamin D (D2, D3)

 $28.49

QuestAssureD™ 25-Hydroxyvitamin D Test - This test measures the levels of Vitamin D in the body, which is crucial for bone health. It checks for Vitamin D activity, except in cases of renal disease. Low levels might indicate a dietary deficiency, poor absorption, or liver issues, leading to bone diseases like rickets and osteomalacia. High levels could cause hypercalcemia. The test specifically measures the two common forms of Vitamin D: 25-OH D3 and 25-OH D2.
