25-OH Vitamin D3/D2 by HPLC (Reversed Phase)

Description
Ordering

The Bio-Rad 25-OH Vitamin D3/D2 by HPLC assay provides precise results for circulating 25-OH Vitamin D3 and 25-OH Vitamin D2 levels. This improved application can be used for simultaneous measurement of the discrete values of 25-OH Vitamin D3 and 25-OH Vitamin D2. The HPLC method allows for precise monitoring of response, useful for daily routine analysis to therapy in patients.

Bio-Rad provides customers with a human serum based calibrator, containing defined Vitamin D3 and D2 values traceable to the Vitamin D Standard Reference Material^® 972 from NIST (The National Institute of Standards and Technologies, an agency of the U.S. Department of Commerce).

Vitamin D is an essential bio-regulator of calcium metabolism and thus significant for bone mineralization. Vitamin D deficiency is a recognized cause of secondary hyperparathyroidism, increased bone turnover and bone loss (ostepenia) in eldery people. Therefore, Vitamin D testing is essential in the management of patients with various disorders of calcium metabolism.

Recent studies have suggested that Vitamin D may play a role in protecting against cancer and in regulating normal immune function. Deficiency has been linked with autoimmune conditions such as type 1 diabetes, multiple sclerosis and rheumatoid arthritis. Vitamin D supplementation to prevent and treat deficiency can be provided in the form of 25-OH Vitamin D3 or 25-OH Vitamin D2. Serum concentration of 25-OH Vitamin D has been accepted as the clinical indicator of a patient's Vitamin D status. In order to identify and correct the deficiency of these 25-OH metabolites, an accurate measurement is essential.

Test characteristics:

Principle: Isocratic HPLC method (Reversed Phase)
Flow rate: 1.1 mL/min
Duration of chromatography: 12 minutes
UV Detection: 265 nm

News & Events

I cannot find the Certificate of Analysis I am looking for. Help!

When using our online Certificate of Analysis search tool, keep the following in mind:

Make sure you entered the correct catalog number and lot/control number in the search fields
If you have a kit, try looking up the Certificate of Analysis using the kit information as well as the information for the individual components
The Certificate of Analysis that you are looking for may not be available via the website. In that case, you can contact your Bio-Rad representative or use the Request Form

If you cannot find the Certificate of Analysis you are looking for, please Contact Us.

Where can I find the catalog number, SKU number, or product number?

The catalog number, SKU number, or product number is printed on your product label. See the sample label below for the location of this information.

Where can I find the lot or control number?

The lot number or control number (one or the other, not both) is printed on your product label. See the sample label below for the location of this information.

Why are Certificates of Analysis not on the Documents tab?

Certificates of Analysis are associated not only with a product, but also with a specific lot of that product. For a given product, there may be several Certificates of Analysis, especially if it is an older product line and has had several lots produced over the years. Using the Certificate of Analysis search tool, you can enter the catalog number and lot/control number for the specific product you have on hand and download the exact Certificate of Analysis you need.

I have a batch number, not a lot/control number. How do I find the Certificate of Analysis for my item?

You can use the batch number in place of the lot/control number. Use the Certificate of Analysis search tool, entering the catalog number as usual and the batch number where the lot/control number would go.

Can I get a Certificate of Analysis even if my item is expired?

Yes. While we do periodically remove Certificates of Analysis for site maintenance purposes, we typically keep them available well beyond a product's expiration date.

Why does it say "Product Name Not Found" for a Certificate of Analysis listed in the search results?

There are Certificates of Analysis that correspond to products that are either discontinued or simply not available on the website. In these situations, the Certificate of Analysis is available for download, but other product details, such as the product name, are not.

Why does it say "Not Available" for a Certificate of Analysis listed in the search results?

In this case, you have entered a valid catalog number and lot/control number and we have located the Certificate of Analysis. However, for some reason, the actual file itself is unavailable.

Please use the Request Form here or contact your local Bio-Rad Representative so that we can send you the Certificate of Analysis.
