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.
Reasons For Conducting the Test. ESR blood testing is called for when there is a suspicion of an inflammatory process underway in the body. The problem with the ESR test with blood is that it doesn't really state what exactly the cause of the inflammation is. For this reason, other tests need to be conducted like complete blood counts for white blood cells and lymphocytes. Another test that is generally conducted is the C-reactive protein test.
