Cause of the Hum. In the U.S. electrical transformers the hum that occurs happens at a frequency of 120 Hz. When vibrations reach this level of repetition, the metal used to construct the transformer internal core begins to give off a noise. The vibration, or hum, is a reaction by the transformer metal to the presence of a magnetic field created as electricity passes through. This process is called magnetostriction.
A high-sensitivity CRP (hs-CRP) test measures low levels of CRP using laser nephelometry. The test gives results in 25 minutes with a sensitivity down to 0.04 mg/L.RP is synthesized by the liver in response to factors released by macrophages and fat cells (adipocytes). It is a member of the pentraxin family of proteins. It is not related to C-peptide (insulin) or protein C (blood coagulation).
This Panel combines 3 tests which can be used to assess a person's risk for cardiovascular disease, heart attack, or stroke. The Comprehensive Heart Health Panel includes a Lipid Panel, C-Reactive Protein High Sensitivity, and Homocysteine test. A Lipid Panel is the standard and most commonly ordered cholesterol test. It measures Total Cholesterol, LDL, HDL, Triglycerides, and VLDL. A CRP High Sensitivity test measures a protein which can be a risk factor for events like a heart attack or stroke. Elevated Homocysteine levels can increase risk for blood clots as well as heart attack or stroke. Turnaround time for the Comprehensive Heart Health Panel is typically 2-5 business days.
