Individual tests

This test measures antibodies against streptolysin O, a substance group A streptococcus bacteria produces. A marked rise or a persistently elevated antibody count indicates that a streptococcus infection or post-streptococcal sequelae are present.
The aPTT is one of several blood coagulation tests. It measures how long it takes your blood to form a clot. When one of your blood vessels is damaged, proteins called clotting factors come together to form clots and quickly stop the bleeding. The aPTT test helps assess how well those clotting factors work, often in conjunction with other tests that monitor clotting factors.
A blood smear is a sample spread on a glass slide and treated with a special stain. Previously, all blood smears were examined under a microscope by laboratory professionals. Now automated digital systems can help examine blood smears. A blood smear helps diagnose and monitor conditions such as blood disorders, sudden kidney failure, and certain cancer treatments.
C3 is part of the complement system, a group of nearly 60 proteins that work with your immune system, playing a role in protecting the body from infections and removing dead cells or foreign materials. This blood test is often used to diagnose or monitor autoimmune disorders like lupus and rheumatoid arthritis.
The complement system consists of almost 60 proteins that work together to promote immune and inflammatory responses, destroy and remove foreign pathogens like bacteria and viruses, as well as damaged “self” materials (e.g. cells and proteins). C3 and C4 are the most frequently measured complement proteins. These tests measure the amount or activity of complement C4 in the blood.
A complete blood count is a common blood test that is often part of a routine checkup. This test can help detect a variety of disorders, including infections, anemia, immune system disease, and blood cancers.
A complete blood count is a screening test for various disease states including anemia, leukemia, and inflammatory processes. This test is analyzed based on blood from the cord.
