Feeling tired all the time? These blood tests help find the cause

Everyone feels tired after a long day, but tiredness that stays for weeks even after proper sleep is worth checking. Very often the reason is something a simple blood test can show, such as low haemoglobin, an underactive thyroid or low vitamin levels. Testing gives you and your doctor facts to work with instead of guessing.

₹825 Book Details

Common reasons doctors look for

Underactive thyroid (high TSH)
Low haemoglobin or low iron stores (anaemia)
Low vitamin B12, common in vegetarians
Low vitamin D from little sun exposure
High blood sugar or undiagnosed diabetes
Poor sleep, stress or long working hours

How to prepare

Thyroid, CBC, B12 and vitamin D need no fasting. If your package includes fasting sugar or a lipid profile, fast 10–12 hours overnight (plain water is fine) and give the sample in the morning.

When to see a doctor

See a doctor soon if tiredness comes with breathlessness on small effort, chest pain, fainting, black stools, heavy bleeding or rapid weight loss. Sudden severe weakness on one side of the body, slurred speech or confusion is an emergency – go to a hospital immediately.

Tiredness & Weakness – FAQs

Which single test is best for tiredness?

There is no single test. Doctors usually start with CBC (haemoglobin), thyroid (TSH) and sugar, and often add vitamin B12 and vitamin D. A full body package covers most of these together.

Can low vitamin D cause tiredness?

Low vitamin D is very common in India and is often linked with tiredness and body aches. A blood test shows your level; your doctor will decide what to do about it.

My reports are normal but I am still tired. What next?

Normal reports rule out several common causes. Discuss sleep, stress, diet and other symptoms with your doctor, who may suggest further tests.

How will I get the report?

The sample is collected at your home and tested at a Thyrocare partner lab. The report is sent on WhatsApp and email.

This page is general information, not medical advice or a diagnosis. Please talk to a doctor about your symptoms.
