What Are The Different Types Of IVD Reagents?

IVD reagents are a type of chemical that can be used in immunoassay or immunodiagnostic testing. The article introduces the different types of IVD reagents, including those that are most commonly used for testing blood, urine, and saliva.

Different Types of IVD Reagents

There are a variety of IVD reagents on the market today, each with its own unique properties that can be beneficial in different ways. Here are three of the most common types: 

1. Conjugated estrogens/progestins – These are typically used as contraceptives, but have also been used as IVD reagents for the past few decades. They have a long half-life and can be administered by injection or orally. Their strongest benefits are in preventing pregnancy, but they can also improve the symptoms of menopause and help to relieve symptoms of other conditions like osteoporosis.

2. Progesterone – This type of IVD agent is typically used to treat women who are pregnant or who are trying to get pregnant. It helps to prevent miscarriage and supports the development of the baby inside the uterus. It also helps to relieve symptoms of various conditions like menstrual cramps, PMS, and fertility problems.

3. Human chorionic gonadotropin (hCG) – hCG is a hormone produced during pregnancy that is often used as an indicator of pregnancy status. It is also used as an IVD agent to help determine the stage of pregnancy. 

How Do We Use IVD Reagents?

Antibodies are used to detect and identify antigens. Antibodies can be specific to one type of antigen or they can be polyclonal, meaning that they are made up of many different types of antibodies.

Nucleic acids are used to detect and identify DNA orRNA. Nucleic acids can be extracted from a biological sample using a variety of techniques, including RT-PCR and PCR.


If you work in the life sciences, then you are undoubtedly familiar with IVD (in vitro diagnostic) reagents. These reagents help scientists test and diagnose various diseases in a lab setting, and they play an important role in the development of new treatments for many illnesses.
