Test results
| Serum Iron | Results
85 µg/dL |
Reference range
30 – 170 µg/dL
|
Explanation
Lower-than-normal levels may mean: Long-term digestive tract bleeding Heavy menstrual bleeding Intestinal conditions that cause poor absorption of iron Not enough iron in the diet Pregnancy (Medline Plus, 2018) |
Status
Mid-range -Normal |
| Ferritin | 4 ng/ mL | 12 – 300 ng/mL | A diet too low in iron
Heavy bleeding from an injury Heavy menstrual bleeding Poor absorption of iron Bleeding in the esophagus, stomach, or intestines (Medline Plus, 2018) |
Low |
| Total Iron binding capacity | 480 mcg/dL | 24m0 – 450 mcg/dL | TIBC is usually higher than normal when the body’s iron supplies are low. This can occur with:
Iron deficiency anemia Pregnancy (late) (Medline Plus, 2018) |
High |
| Transferrin Saturation | 10% | 20 – 55% | Lower-than-normal TIBC may mean:
Anemia due to red blood cells being destroyed too quickly (hemolytic anemia) Lower-than-normal level of protein in the blood (hypoproteinemia) Inflammation Liver disease, such as cirrhosis Malnutrition Decrease in red blood cells from the intestines not properly absorbing vitamin B12 (pernicious anemia) Sickle cell anemia (Medline Plus, 2018) |
Low |
| Hormone | ||||
| T3 | 7 pmol/L | 3.5 – 7.8 pmol/L | A higher-than-normal level of T3 may be a sign of:
Overactive thyroid gland (for example, Graves’ disease) T3 thyrotoxicosis (rare) Toxic nodular goiter Taking thyroid medicines or certain supplements (common) Liver disease A high level of T3 may occur in pregnancy or with the use of birth control pills or estrogen (MedlinePlus 2018) |
Normal / High |
| T4 | 10 pmol/L | 9 – 25 pmol/L | Low levels of any of these tests (total T4, free T4, or free T4 index) may indicate an underactive thyroid, also known as hypothyroidism (MedlinePlus 2018) | Normal / Low |
| TSH | 15 mIU/L | 0.5-5.0 mlU/L | A higher-than-normal TSH level is most often due to an underactive thyroid gland (hypothyroidism). There are many causes of this problem (Medline plus 2018) | Very High |
Diagnosis
The likely diagnosis based on the results is Hypothyroidism with Anaemia.
