Analyzing a sample of bone marrow may reveal what's causing your blood problem. Bone marrow biopsy is commonly used to diagnose a variety of blood problems â both noncancerous and cancerous â including blood cancers, such as leukemia, lymphoma and multiple myeloma. A bone marrow biopsy may also detect cancers that started elsewhere and traveled to the bone marrow.
why do i need a urine culture? Do you suspect you have a urinary tract infection or are you having difficulty or pain on urination and a frequent urge to urinate? A urine culture is usually ordered when a person has symptoms typical of a UTI such as pain or burning when urinating and frequent urges to urinate. Sometimes antibiotic therapy may be prescribed without requiring a urine culture for young women who display symptoms.
For example, urine infection is generally diagnosed based on results of urinalysis. However, urine culture is often ordered as a follow-up test to identify the bacteria that may be causing the infection. Other examples include kidney stones, inflammation or the kidneys (glomerulonephritis), or muscle breakdown (rhabdomyolysis).
