Power Analysis, Statistical Significance, & Effect Size. If you plan to use inferential statistics (e.g., t-tests, ANOVA, etc.) to analyze your evaluation results, you should first conduct a power analysis to determine what size sample you will need. This page describes what power is as well as what you will need to calculate it.
1 Mean corpuscular volume (MCV) is a measurement of the average size of a single red blood cell.  Mean corpuscular hemoglobin (MCH) is a calculation of the average amount of hemoglobin inside a single red blood cell.
A positive PCR test means you are currently infected with hepatitis C. Please note: a single negative PCR test does not mean you do not have hepatitis C. Sometime the virus level may be too low for the test to detect it in the blood.If your clinician thinks you have hepatitis C, the PCR test should be repeated.ntibody Tests The first blood test usually done to look for hepatitis C is an antibody test (anti-HCV). A positive anti-HCV result should be verified with a second more accurate test called RIBA ((Recombinant Immunoblot Assay) because anti-HCV tests may produce false positive results.
