- ESR Blood Test: Erythrocyte Sedimentation Rate Westergren$49.44
The erythrocyte sedimentation rate (ESR or sed rate) is the rate at which red blood cells sediment in a period of one hour. It is a common hematology test and is a non-specific measure of inflammation. To perform the test, anticoagulated blood is traditionally placed in an upright tube, known as a Westergren tube, and the rate at which the red blood cells fall is measured and reported in mm at the end of one hour. Elevated levels of ESR are usually found in people who have different types of diseases, such as autoimmune disease, anemia, kidney disease, cancer, and other health complications.
Learn More - ApoB Blood Test$34.65
ApoB Blood Test has been reported to be a powerful indicator of Coronary Artery Disease (CAD). In some patients with CAD, APO B is elevated even in the presence of normal LDL cholesterol. Instead of non-HDL-C levels, ApoB levels may be used to check how well lipid treatment is working. Non-HDL-C is the total cholesterol concentration minus the amount of HDL. A healthcare practitioner may order both an lipoprotein a (associated with high-density lipoprotein (HDL), the "good" cholesterol) and an apo B to determine an apo B/apo A-I ratio. This ratio is sometimes used as an alternative to a total cholesterol/HDL ratio to evaluate risk for developing CVD.
