I don t think I have ever seen yoh, just yo. So I think it means, yarn over hook. So what this means is that you yarn over the hook like you were going to do a double crochet stitch. Then you insert the hook into the designated stitch, hook the yarn with the hook and draw it through the stitch.
Sed rate (erythrocyte sedimentation rate) Overview. Sed rate, or erythrocyte sedimentation rate (ESR), is a blood test that can reveal inflammatory activity in your body. A sed rate test isn't a stand-alone diagnostic tool, but it can help your doctor diagnose or monitor the progress of an inflammatory disease. When your blood is placed in a tall, thin tube, red blood cells (erythrocytes) gradually settle to the bottom. Inflammation can cause the cells to clump.
ESR is used to help diagnose certain specific inflammatory diseases, temporal arteritis, systemic vasculitis and polymyalgia rheumatica. A significantly elevated ESR is one of the main test results used to support the diagnosis. This test may also be used to monitor disease activity and response to therapy in both of the above diseases as well as some others, such as systemic lupus erythematosus (SLE) .
