Can a CBC (blood test) show leukemia always?

Can a CBC (blood test) show leukemia always?

Yes, most times: A leukemia typically begins in the bone marrow and will often show effects on the CBC as the cancer cells spill over into the circulating blood. On rare occasions leukemia may be still limited in the bone marrow, so we make a diagnosis by taking a bone marrow sample. ...Read more

Could a CBC (blood test) show leukemia accurately always?

Could a CBC (blood test) show leukemia accurately always?

Sometimes: Sometimes but not always. Leukemia, a form of blood and bone marrow cancer, is frequently detectable in the blood; however, especially if early in the course of the disease, leukemic cells may be confined to the bone marrow and not cross into the blood in sufficient numbers to be detected by a cbc. Ultimately, the complete diagnosis and prognosis of leukemia relies on bone marrow examination. ...Read more

Can CBC show lymphoma? or could it at least make the doctor request other tests for lymphoma?

Can CBC show lymphoma? or could it at least make the doctor request other tests for lymphoma?

Maybe: Malignant lymphoma cells only enter the blood late -- if they were there early, it would be a leukemia. Anemia, especially if coombs-positive, raises suspicion for lymphoma. The classic triad of fever, weight loss, and night sweats of course suggests lymphoma, but the key is the discovery of a mass in a lymphoid area. Hodgkin's is common in youngsters; non-Hodgkin's in older folks. ...Read more

What is the difference between a CBC lab test with blood and a blood culture, and which one shows more?

See below.: A complete blood count shows the types of white blood cells present,which can tell whether an infection is bacterial or viral; it also includes a measure of your hemoglobin and hematocrit, which is an indirect measure of anemia, and platelet count.

Cbc: Yes, there are some abnormal features that you can see in CBC ( and peripheral blood smears) that would increase your suspicion towards certain blood cancer-for instance- circulating blast cells ( immature white blood cells) in acute leukemia, and other features that you can see in chronic leukemia- i.e. Cml, cll. You can not see any sign of solid cancer from cbc, however, . ...Read more

If i had a weak immune system would my CBC test show it?

If i had a weak immune system would  my CBC test show it?

Not necessarily: A complete blood count only looks at white blood cells, red blood cells and platelets. The immune system can become compromised with a myriad of conditions (diabetes for example - where the CBC is often normal) speak to your physician why you think your immune system is compromised and go from there. In the meantime do not forget that food is medicine. Eat healthy, exercise, get adequate sleep. ...Read more

I had a X-ray which was clear if I had chest discomfort would it show up on X-ray also a CBC and sed blood tests all clear anything to worry sbout?

Hard to say: There are a lot of causes of chest pain. (I'm assuming you have chest pain.) Finding the cause requires the combination of information and testing. I don't have all the information here. The tests you have rule out some things, like inflammatory and infectious problems, popped lung, and pneumonia. But they don't rule out other things. You need to see a doctor in person. ...Read more

My doctor said that the blood test will show iron in it but i don't see iron listed in the results?  Cbc and differential

Indirect information: The CBC gives information about, among other things, red blood cell number, size, and variability of size. If all of those are normal, the likelihood of iron deficiency is virtually zero. Iron excess, in contrast, can be present with a normal CBC. ...Read more
