D-dimers are small fragments of proteins detected in the blood after breaking down a blood clot. D-dimer levels are used to detect these blood clots. D-dimer test is used in diagnosing blood clots deep inside the veins, to check for blockage in the arteries and lungs, which can affect the blood flow to various organs and tissues as well as increase the chances of a Heart attack. D-dimer test is recommended for someone with chest pain, increased heart rate, difficulty in breathing, seizures, blood in cough, bleeding gums, nausea, decreased urination, muscle pain, leg pain, and swelling. Elevated levels of D-dimer protein are seen in severely infected COVID19 patients, and hence it is used as a marker to predict the severity of the disease. Elevated D-dimer levels are also noted in older ages, pregnancy, liver and kidney diseases. Thyrocare offers the Dimer test at the most affordable price. Sample collection at home available.
