Elevated red cell volume in North Indian students.

In a survey for beta-thalassemia carrier status among students in the State of Punjab in India, a surprisingly large number were found to have an elevated red cell volume over 99 fl. The finding was predominantly but not exclusively in females. Similar student surveys from other states showed less macrocytosis. Follow-up tests in a group of affected students were carried out. Volunteers were asked to modify their diet then after six months they were provided with oral vitamin B12. The resulting changes are reported and the implications of the probable vitamin B12 and or folic acid deficiency are considered.

Use of the WHO hemoglobin color scale in family welfare clinics in India.

A situation is reported for the use of the WHO color scale for the measurement of hemoglobin, which was introduced into India in 1996. Charity family welfare clinics held at a medical college hospital in North India offer free sterilization by tubal ligation under local anesthetic to women following a preliminary screening. An obligatory test of the hemoglobin level is required and must be above 7.0 g/dl for the operation. Some clinics attract large numbers, and the card gives a cheap, rapid and reasonably accurate test, adding to the smooth running and reduction of waiting time. It has proved satisfactory over a 2-year period; 2.3% of participants were shown to have a hemoglobin level of 7 g/dl or less.
