    Blood Chemistry

    Blood chemistry assists in measuring certain substances present in the blood, such as proteins, glucose, and enzymes.


    Coagulograms measure the blood’s ability to clot and how long it takes. It helps assess excessive bleeding and clotting issues.


    These tests can evaluate a variety of blood conditions, including infections, anemia, inflammation, and hemophilia, among others.


    Immunoassay tests help measure certain substances in the blood through the use of an antibody or antigen.
