Fibrinogen is a protein found in the blood, which is involved in blood clotting and its normal levels reflect the clotting ability of the blood. It is usually measured as a part of coagulation tests when a person has symptoms suggestive of unexplained or prolonged bleeding. Some doctors also use its levels to evaluate the risk of heart disease, though this is not too common.
This protein is an acute phase reactant i.e. its level in the blood show a steep rise in any condition that causes inflammation or tissue damage in the body. It is thus, a non-specific marker of underlying inflammatory states and does not tell the cause or site of the underlying disease process. The levels return to normal once the primary problem is over. Common causes for its elevation include - acute infections, inflammatory disorders, injury, cancer, diseases involving blood vessels like stroke or heart attack etc. Many drugs too cause its level to rise like the use of oral contraceptives containing oestrogen, steroids and even cigarette smoking.
Your elevated fibrinogen level will not affect the IVF procedure. Its elevated levels need to be interpreted in the light of your symptoms and medicines that you are taking.
