Significance of abnormal blood color07/25/2007 |
My venous blood is extremely dark in color-- darker than any blood I`ve ever seen, and I`ve seen a lot of blood. CBC, H&H, and other routine blood tests appear normal. Are there any conditions associated with dark brown, almost black blood color?
While there is a rare condition that can cause the blood to look brown (methemoglobinemia), it is typically associated with the administration of one of several medicines that can cause this, and also makes the patient very symptomatic (short of breath). With all the tests normal, and I assume you having no symptoms, it is unlikely that there is a significant underlying condition that would lead to the blood looking this color.
I hope this helps out somewhat.
