When a hemoglobin can read wrong
Dehydration concentrates the blood and pushes hemoglobin up; a lot of IV fluid or pregnancy dilutes it. Smoking and altitude raise it, and right after sudden blood loss it can still look normal for a few hours.

Questions
Is a hemoglobin of 14.5 g/dL normal?
A hemoglobin of 14.5 g/dL is in the typical adult range. The usual range is about 12.0 to 15.5 g/dL in women and 13.0 to 17.5 g/dL in men.
What is 14.5 g/dL in g/L?
145 g/L. Labs in different countries print Hemoglobin in different units; the meaning is the same.
What is a dangerously low hemoglobin?
The WHO calls under 8.0 g/dL severe anaemia. How urgent it is depends on symptoms and how fast it fell, so a result that low is a call to your doctor the same day.
Worked out by LifeFrom from the WHO's 2024 haemoglobin guideline, and not yet reviewed by a clinician. For your own understanding: only a lab test, read by your clinician, diagnoses anything.
