On Greg's last visit to his doctor, he complained of feeling tired. Sandra, the registered nurse, withdrew 6.5 mL of blood, which was sent to the lab and tested for iron. The normal range for serum iron in men is 80 to 160mcg / dL. Greg 's iron test showed a blood serum iron level of 39mcg / dL which indicates that Greg has iron-deficiency anemia.
Choose an equality for Greg's serum iron level
39 dL of iron= 1 mcg of blood
39 mcg of iron =1 dL of blood
39 mcg of blood= 1 dL of iron
39 dL of blood =1 mcg of iron
39 mcg of blood = 1 dL of iron
39 mcg of iron = 1 dL of blood
The correct equality for Greg's serum iron level is: 39 mcg of iron = 1 dL of blood.
To determine this, we look at the given information that Greg's iron test showed a blood serum iron level of 39 mcg / dL. This means that there are 39 micrograms (mcg) of iron in 1 deciliter (dL) of blood. So, we can say that 39 mcg of iron is equal to 1 dL of blood.
