Abstract

Objective: To high light the importance of laboratory investigations for students and encourage them to participate in research.
Methodology: This cross sectional study was carried out at Islamabad Medical and Dental College Islamabad for a three months period from April 1, 2014 to June 30, 2014. Students with age 18-20 years were chosen by convenience sampling for sample collection. Verbal consent was taken from candidates before sample collection. Packed cell volume (PCV) was measured by using Micro Hematocrit method and hemoglobin (Hb) concentration by Sahli’s acid haematin method. Data were analyzed using SPSS version 20.
Results: Out of 106 students, there were 32 males and 74 females. Male participants had significantly greater Hb concentration and PCV as compared to females (p=0.05).
Conclusion: Both Hb and PCV were significantly higher in males as compared to females of almost same age. For improving Hb concentration, dietary sources of iron and iron supplements may be used for better health of future generation.

Key words: Hemoglobin (Hb), packed cell volume (PCV), anemia, polycythemia, homeostasis.
