What is a CD33 (Myeloid Cell Marker) Test in Lucknow ?
What is CD33 (Myeloid Cell Marker)?
This test measures the CD33 protein on the surface of certain white blood cells called myeloid cells. CD33 helps identify and classify cells that come from the myeloid lineage in the bone marrow and blood.
What does CD33 (Myeloid Cell Marker) measure?
It is important because abnormal levels or patterns of CD33 are linked to blood cancers such as acute myeloid leukemia and some myelodysplastic syndromes. Doctors use CD33 testing to help make a diagnosis, decide on treatment options, and monitor response to therapy. It can also be used to track minimal residual disease after treatment and to guide targeted therapies that aim at CD33-positive cells.
What symptoms suggest CD33 (Myeloid Cell Marker) may be needed?
A doctor may recommend CD33 (Myeloid Cell Marker) when a patient reports persistent fatigue, hair thinning, brittle nails, bone or joint pain, frequent infections, poor wound healing, numbness or tingling in the hands or feet, and low mood or poor concentration. In Lucknow, you can book this test online with home collection available in Mahanagar, Chinhat, and beyond.
How is CD33 (Myeloid Cell Marker) performed?
At a GetVisit-partnered lab in Mahanagar or Chinhat, Lucknow, a certified phlebotomist cleans the inner elbow, locates a vein, and draws the required blood (typically 5 to 10 mL). The procedure takes 3 to 5 minutes. You feel a brief pinch at insertion and mild pressure during collection, then can eat, drive, and resume all activities immediately afterwards.
How accurate is CD33 (Myeloid Cell Marker)?
Accuracy for CD33 (Myeloid Cell Marker) depends on timing: taking the supplement being measured shortly before the test inflates the reading, so hold it for about 48 hours. GetVisit's NABL labs serving Mahanagar and Chinhat, Lucknow maintain strict quality control.
Are there any risks to CD33 (Myeloid Cell Marker)?
There are no significant risks beyond those of a standard blood draw. For your appointment in Mahanagar or Chinhat, Lucknow, drink 2 to 3 glasses of water beforehand and stay seated for 2 to 3 minutes afterwards, as vasovagal fainting (rare) is more likely if you are fasting, anxious, or dehydrated. Tell the phlebotomist if you have fainted during previous draws.
Did you know?
CD33 (Siglec-3) is a myeloid-lineage surface marker expressed on mature myeloid cells, monocytes, granulocytes, and on myeloid progenitors and many acute myeloid leukemia blasts, but typically absent on lymphoid cells.
CD33 (Myeloid Cell Marker) Test Preparation in Lucknow
Managing medication:
Avoid supplements of the nutrient being measured for a day or two before the test; taking one shortly before can inflate the reading.
Fasting instructions:
Eat and drink as you normally would; fasting is not required. Try to avoid a very fatty meal or alcohol right before the appointment.
Timing:
Book whenever is convenient; for fasting or hormone tests an early-morning slot is ideal. GetVisit covers Indira Nagar, Charbagh, and all of Lucknow.
What to bring along:
Have your doctor's referral and photo ID ready; earlier reports for the same test are useful for tracking trends.

Why Take a CD33 (Myeloid Cell Marker) Test in Lucknow ?
When does a doctor order CD33 (Myeloid Cell Marker)?
CD33 (Myeloid Cell Marker) is often included in flow cytometry panels and leukemia diagnostic profiles. Doctors may order it when a patient has symptoms like unexplained fatigue, easy bruising, infections, or abnormal blood counts.
Who should get CD33 (Myeloid Cell Marker) done in Lucknow?
Vitamin D deficiency is common in Lucknow due to indoor lifestyles and winter smog that reduces UV exposure. B12 and iron deficiency are frequent among the city's vegetarian residents across Gomti Nagar, Aliganj, and Indira Nagar. Those who benefit most from regular CD33 (Myeloid Cell Marker) testing include people on restrictive diets, those recovering from illness, and anyone with persistent tiredness. Confirming a deficiency in Lucknow allows correctly dosed supplementation rather than guesswork.
What conditions can CD33 (Myeloid Cell Marker) help diagnose?
It helps diagnose and monitor conditions such as acute myeloid leukemia and myelodysplastic syndromes. Abnormal results usually reflect disease in the bone marrow or blood and can be influenced by certain treatments; a strong family history of blood cancer may increase the need for testing.
What do CD33 (Myeloid Cell Marker) results mean?
Serum ferritin below 12 ng/mL: iron deficiency. Ferritin 12–30 ng/mL: iron depletion without yet affecting haemoglobin. Folate below 3 ng/mL: folate deficiency. Zinc below 70 µg/dL: zinc deficiency, associated with impaired immunity and wound healing.
How often should CD33 (Myeloid Cell Marker) be repeated?
After starting supplementation, recheck at 8 to 12 weeks to confirm levels are correcting, then every 6 to 12 months once replete. People with ongoing risk factors, restrictive diets, malabsorption, or limited sun exposure, benefit from annual screening even without symptoms.
What happens after CD33 (Myeloid Cell Marker) results are ready?
Your GetVisit digital report is delivered to your phone as soon as results are authorised. Share it directly with your doctor via the app, or book a consultation with a GetVisit-verified specialist on the same platform. Critical values outside a safe range are flagged by the laboratory for urgent clinical review.
