What tests do I need right after being diagnosed with Leukemia

Tests After a Leukemia Diagnosis

After being diagnosed with leukemia, your care team will order several important tests to understand your specific type of leukemia and plan your treatment. Here's what you can expect:

Initial Diagnostic Tests (Already Done or Being Done)

You've likely already had:

• Bone marrow aspirate and biopsy — samples of bone marrow removed to confirm the diagnosis and examine cell types
• Complete blood count (CBC) with differential — measures your red blood cells, white blood cells, and platelets to see how many abnormal cells are present
• Blood tests — to check basic health and organ function

Tests to Determine Your Specific Subtype

According to the NCCN Guidelines for Patients: Acute Myeloid Leukemia, these tests are essential for understanding which type of leukemia you have:

Genetic and biomarker testing on your leukemia cells to look for:

• Specific gene mutations (like FLT3, NPM1, or others)
• Chromosome changes (like translocations or deletions)
• These findings help doctors predict how your leukemia might behave and which treatments will work best

Methods used include:

• Karyotype — a picture of your chromosomes to spot abnormalities
• FISH (Fluorescence in situ hybridization) — uses special dyes to find small chromosome changes
• NGS (Next-generation sequencing) — detailed DNA analysis that can catch mutations other tests might miss
• PCR (Polymerase chain reaction) — very sensitive test that can find 1 abnormal cell among 100,000 normal ones

Tests to Check Your Overall Health

Comprehensive metabolic panel (CMP) — measures:

• Kidney function (creatinine, BUN)
• Liver function
• Electrolytes (minerals your body needs)

Additional blood tests:

• Liver function tests (LFTs) — to see how well your liver is working
• Uric acid and LDH (lactate dehydrogenase) — high levels can indicate fast-growing cancer cells
• B12 and folic acid levels — important for blood cell formation
• Blood clotting tests — leukemia can affect your body's ability to clot properly
• HLA typing — if a bone marrow transplant might be an option later

Tests to Check for Leukemia Spread

Imaging tests (depending on your situation):

• Brain CT or MRI — to check if leukemia has spread to the brain or spinal fluid
• Chest X-ray or CT — to look at your lungs and chest
• PET/CT scan — in some cases, to find leukemia outside the bone marrow

Lumbar puncture (spinal tap) — if your doctor suspects leukemia in the fluid around your spine and brain

Tests to Check Your Heart

Heart tests may include:

• EKG (electrocardiogram) — checks your heart's electrical activity
• Echocardiogram — uses sound waves to see how well your heart pumps

These are important because some leukemia treatments can affect heart function.

Other Important Tests

• Fertility assessment — if you're of childbearing age, discuss with your care team how treatment might affect your ability to have children
• Performance status evaluation — your doctor will assess your overall health and ability to handle treatment

Important Timeline Note

According to the NCCN Guidelines, testing takes time — it might take weeks for all results to come back. This is normal. Your care team will discuss results with you once they're complete, so try not to worry if you don't hear everything immediately.

Questions to Ask Your Care Team

1. What type of leukemia do I have, and what do the genetic tests show?
2. Which tests will I have, and how often will they be repeated?
3. When will my results be ready, and when can we discuss them?
4. Do I need any additional tests before starting treatment?
5. Will my insurance cover these tests?
