Dangerously low hemoglobin levels that require transfusion are 7 grams per deciliter for ICU patients and 8 milligrams per deciliter for most other patients, according to U.S. News. Low hemoglobin is anything below 13.5 grams per deciliter for men, and 12 grams per deciliter for women, according to
A high hemoglobin count can indicate serious medical conditions such as kidney failure, liver cancer and heart failure, according to Mayo Clinic. High hemoglobin can also result from residing in high-altitude environments. High hemoglobin counts are often expected by physicians when testing for cert
A low hemoglobin count, also known as anemia, is caused by pregnancy, a menstrual period, a diet low in iron, blood loss, or a disease that causes the body to produce fewer red blood cells or to destroy red blood cells.
