25-Hydroxyvitamin D2 / D3 Serum LC-MS/MS APCI Analysis Kit

 25-Hydroxyvitamin D2 / D3 Serum LC-MS/MS APCI Analysis Kit
CE-IVD certified and suitable for any kind of LC-MS/MS instrument

 

The Zivak Vitamin D2/D3 analysis kit can be used in combination with the Zivak-Multitasker as well as manually. Analysis run time for the manual version is 1.7 minutes. Due to the efficient and quite smart procedure of the Zivak-Multitasker, the automated version guarantees also to receive results in 1.7 minutes per test, including sample preparation-, sample injection- and analysis run time. Additionally, high accuracy is being rectified through NIST (National Institute of Standards and Technology) with an accuracy of 96%.

Quantitative LC-MS/MS analysis kit for 25-hydroxy metabolites of Vitamin D2 and D3 in human serum samples.

Vitamin D, commonly known as the “sunshine vitamin”, is essential for maintaining calcium metabolism and bone health. The major physiologic function of Vitamin D is to maintain the bloodcalcium and phosphorus levels within the normal range in order to maintain metabolic functions that are essential for most life processes, Vitamin D3 and Vitamin D2 are metabolised to 25-OH-Vitamin D3 and 25-OH-Vitamin D2 in the liver by the 25-OHase enzyme. The quantitation of these metabolites is widely used for determining of Vitamin D status in human. The Vitamin D status has a clinical significance in a variety of disorders which related to hormones. The measurements of the serum concentration of 25-OH-Vitamin D3 and 25-OH-Vitamin D2 have been used for differential diagnosis of hypocalcemic and hypercalcemic metabolic bone disorders.

The analysis of these metabolites is considered to be difficult. Some reasons of the difficulties are below;

  • The low concentrations of 25-OH Vitamin D metabolites in serum. (level of µg/L)

  • The low stability in the presence of light and heat.

  • The presence of other metabolites which have chemical similarity.

  • The large amount of other related neutral lipids (such as cholesterol)

25-OH Vitamin D2-D3 LC-MS/MS Analysis Kit was developed for rapid, sensitive and reliable quantitative detection of the 25-OH Vitamin D2-D3 concentrations in human serum samples and it gives results in 1.7 minutes with minimal sample preparation. Main methods and procedures that we selected are based on EN ISO 13485 and 98/79/EC.
