What does High LAMBDA Free light chains?

High LAMBDA free light chains refer to elevated levels of lambda light chains in the blood, which are part of immunoglobulins produced by plasma cells. These elevated levels can indicate various conditions, including multiple myeloma, a type of blood cancer, or other plasma cell disorders. Measuring free light chains is important for diagnosing and monitoring such diseases, as an imbalance between kappa and lambda light chains can provide insights into the underlying pathology.
