If Fibrin clot forms in serum layer of blood specimen?

If a fibrin clot forms in the serum layer of a blood specimen, it can indicate that the sample has been contaminated with tissue fluid or that the blood has not been properly processed.

- During the process of blood collection and preparation, it is important to avoid any contamination of the specimen with tissue fluids or other substances, as this can affect the accuracy of the test results.

- Blood samples should be handled carefully and processed promptly to minimize the risk of clotting. If a clot forms, it can interfere with the separation of the serum from the cellular components of the blood, making it difficult to obtain an accurate analysis.
