Brief summary

The clinical evaluation of anemia is usually done by examination of the palpebral conjontivae coloration. This appreciation remains crude and largely observer dependent, as no reference scale was successfully proposed,. A Hb visual scale allowing the assessment of the degree of clinical anemia has been developed. Its use has been validated so far in small patient groups in the following settings: blood donation, cardiac surgery, oncology and consultation of general practitioners. The objective of the present investigation is to validate the use of a Hb visual scale for the clinical evaluation of anemia in patients with kidney disease patients
