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.
While these symptoms can include a number of disorders, the ESR is used as a guideline to begin the diagnosis process. An ESR test measures the inflammation in the body. Used along with family history and other tests, a single ESR test may not be sufficient for a diagnosis.
