| Summary: | Background. Serum ferritin is the most common parameter
used to assess iron status in newborn, can be rising in
acute infection, inflammation or malignancy. A new
parameter such as Ret-He consider be more accurate,
less expensive, easier, faster and earlier detected to
assess iron status.
Objectives. To knows correlation between Ret-He and
Serum Ferritin in newborn at RS PKU Muhammadiyah and
whether Ret-He can be an alternative indicator of iron
deficiency.
Method. Cross-sectional with direct observation is
conducted. Serum Ferritin and Ret-He is taken directly
from blood cord immediately after baby born at RS PKU
Muhammadiyah, Bantul.
Result. Among 313 newborns, 56 excluded due to
incomplete data. In total 257 included with 94,6% have
normal ferritin status with reference range 6-400 μg/L,
99,3% have Ret-He level above cut off point 29 pg. With
p= 0,124(p> 0,05), r= 0,095(r= 0,0 - <0,2), and slops
of dots on scatter graph without straight line formed
shows no any significant relationship between Ret-He
with Serum Ferritin.
Conclusion. There is no any significantly correlation
between Ret-He and serum ferritin in newborn. Ret-He
was not shown a positive chance to be alternative
indicator to assess iron status of newborn due to lack
of previous studies in newborn.
