Yes. In anemic patients, oxygen delivery decreases and oxygen extraction is increased. This leads to decreased venous hemoglobin saturation and a lower tissue oxygen saturation

Dr. Dhankecha Suggests...

Take a PROTHROMBIN TIME (PT/INR) Test or Take a ALLERGY, CAT DANDER Test

I am a 41 year old female experiencing abdominal pain and severe back pain. My recent reports are concerning, especially my iron and urine tests, but I am unsure who to consult for a proper diagnosis. My fasting blood sugar is 120.7, HbA1c is 6.20, CRP is 1.0, cholesterol is high (under medication for 7 years), GGT is 42.2 (I have no gall bladder), serum iron is 48.1, transferrin saturation is 13.72, and kidney function is normal. However, urine tests show blood positive with 6-7 RBCs. I have not attached all the reports. Please advise whom I should see for further evaluation and management.
