Immunoserology Practice Test 2025 – The Complete All-in-One Guide to Exam Success!

Antibodies, also known as immunoglobulins, are composed of heavy and light chains. The light chains are essential components that help determine the specificity and function of the antibody. There are two distinct types of light chains found in antibodies: kappa and lambda.

Kappa light chains are the more prevalent type, whereas lambda light chains are less common but still play a crucial role in antibody structure and activity. The presence of these two types provides diversity in antibody formation, enabling the immune system to effectively recognize and respond to a vast array of antigens.

The correct identification of kappa and lambda light chains is particularly important in clinical settings, such as in the diagnosis of various blood cancers and conditions that affect the immune system. The measurement of kappa and lambda light chains can provide valuable information regarding disorders like multiple myeloma and other immunological conditions.

Other options provided contain incorrect combinations that do not represent the true types of light chains present in antibodies.
