Could Blood Test Detect Lymphoma
Only a few cancers: Unfortunately, there are very few cancers that can be detected through blood tests. These include prostate cancer and leukemia. Some other cancers have tumor marker tests, such as breast cancer, ovarian cancer, colon cancer, pancreatic cancer, and others but these are to monitor, not detect the cancer. ...Read moreSee 1 more doctor answer
Usually an adept: Hand examining the scrotum is the beginning, but you are likely referring to Alpha -feto-protein (embryonal and yolk sac tumors) and HCG (human chorionic gonadotropin) choriocarcinoma, germinoma, and teratoma. Seminoma may not produce either, and never afp. These occur in all ages, but especially young men teens and twenties. ...Read moreSee 2 more doctor answers
Testing: Chlamydia tests include a culture that may take 5 to 7 days to grow. A direct fluorescent antibody test looks for antigens. A nucleic acid hybridization test or a nucleic acid amplification test looks for chlamydia dna &enzyme –linked immunosorbent assay. Directing sampling uses fluids from cervix, urethra throat, eye (whichever area is impacted). Urine testing is also possible. ...Read more
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
No, may need biopsy.: A blood test can detect some lymphomas with high lymphocyte peripheral blood count, but fine needle aspiration of some lymph nodes, and/or a lymph node biopsy may be needed. This can be used to distinguish between types of lymphoma, like hodgkin's vs. Non-hodgkin's, mantle cell vs. B-cell, t-cell, infection, cancers, etc.. Specific markers for b and t cells are also used. ...Read more
Yes it can: The TPHA test (Treponema pallidum hemagglutination) is a confirmatory test for syphilis. Usually it is done only after a positive screening test, such as the VDRL, RPR, or an EIA test. If you have had negative results on one of these plus the TPHA, you can be 100% certain you don't have syphilis and probably never did. ...Read more
Yes.: There are many forms of leukemia. Some are "acute" and present quickly. These can be serious / fatal without treatment. Other types of leukemia are "chronic' and can be present for years without the patient knowing / being diagnosed. One of the first tests used to diagnose any leukemia is a complete blood count and review of a peripheral blood smear under the microscope. Hope this helps. ...Read more
No blood test: There is no blood test to detect amyloidosis. Sophisticated laboratory techniques called electrophoresis or free light chain assays may reveal early evidence of some amyloid proteins. A biopsy is needed to confirm a diagnosis of amyloidosis and determine the specific type of protein involved in the disease. ...Read moreSee 2 more doctor answers
Blood tests for clot: There are no specific blood tests that will be definitive to prove a clot exists. Ultrasound, CT andMR are the diagnostic modalities to prove a clot. D-dimer is a blood test that can be used to identify clot formation but it is very non specific. If negative there is good evidence that a clot does not exist but d-dimer can be positive for many reasons not related to a clot. ...Read moreSee 1 more doctor answer
Need other tests.: Blood tests might show signs pointing to lymphoma, like many lymphocytes, and lymphoblasts, but other signs are seen, like lymphadenopathy (enlarged lymph nodes). Also, there are many kinds of lymphomas, like follicular, and mantle cell, and they need tests like biopsy and flow cytometry to distinguish them, so other tests are needed. ...Read more
