What is a Complete Blood Count (CBC) test?
A CBC test is a basic blood screen that measures various components of your blood, including red blood cells (which carry oxygen), white blood cells (which fight infections), and platelets (which help blood clot).
Does a CBC test require fasting?
No. A standalone CBC test does not require fasting. You can eat and drink normally. If combined with other metabolic profile tests, fasting may be required.
How much does a CBC test cost?
A complete CBC test with home collection starts at ₹ 299. The test includes red/white cell counts, hemoglobin, platelets, and differential index parameters.
What does a high white blood cell (WBC) count mean?
A high WBC count typically indicates that your body is fighting off an infection, inflammation, stress, or an allergic reaction. In rare cases, extremely high levels can point to bone marrow disorders.
What causes low hemoglobin in a CBC report?
Low hemoglobin indicates anemia, most commonly caused by iron deficiency, vitamin B12/folate deficiency, chronic disease, or blood loss. It leads to symptoms like fatigue, weakness, and pale skin.
