Blood

Blood is a bodily fluid consisting of plasma, blood cells, and platelets that is circulated by the heart through the vertebrate vascular system, carrying oxygen and nutrients to and waste materials away from all body tissues. In many species, it also carries hormones and disease-fighting substances. In this category, you will find questions about the blood in your body, including blood types, blood diseases, and the function of blood.

Can low hemoglobin cause muscle pain?

Yes, low hemoglobin can cause muscle pain. Hemoglobin is a protein and is attached to red blood cells. Its job is to carry oxygen to the body's tissues. Without oxygen the tissues (including muscle) experience ischemia which is painful. Ischemia is what causes the pain a person has when they have a heart attack, for instance. So if a person's red blood cells are not carrying oxygen (because their hemoglobin levels are low enough), they would have muscle pain. ...

What does a 314 white blood cell count mean?

It would be helpful to know what the units of measure are. In hematology, the reference range for a WBC is 4,500-11,000/mm3 ; however, the count is usually reported out in SI units ( for example, 4.5 x 109 /L) or Conventional Units (4.5 x 103/uL). So, on a lab report, a range of 4.5-11.0 is the normal range using these units of measure. If your report is using the standard units of measure, then a WBC of 314 is considered a...

Do you have to fast for an A1C blood test?

No. The A1C test measures the amount of glucose bound to hemoglobin in the red blood cells. This binding process is related to the concentration of glucose present and the time of exposure. New cells are constantly created to replace old cells that are removed. Thus, the test meaures an average value of the glucose exposure over the life of the red blood cell (about 4 months). So, a one-day change, due to fasting for example, represents only a small change (one...
