However, these are not useful for diagnosing the flu at the time of infection as it takes several days for the body to develop antibodies.

Can I get a blood test if I have the flu?

Proper serological testing for diagnosis of influenza requires paired acute and convalescent sera collected 2-3 weeks apart, with reliable testing at a limited number of public health or research laboratories to assess a 4-fold or greater rise in influenza virus strain-specific antibodies.

What is the most accurate test for the flu?

Make sure you're well when you get your bloods taken.

That is, don't have your fasting blood taken if you've got a head cold, sore throat or are otherwise unwell. Similarly to when you over-fast, if you have bloods taken when you're not well, some of the results can be skewed.

What is the blood test for the cold and flu?

Molecular assays

Molecular flu tests detect the genetic material of the flu virus in a respiratory sample. These tests are more accurate than rapid antigen tests. They can detect smaller amounts of the flu virus.

Can a CBC detect flu?

The CBC test proves to be a valuable tool when diagnosing infections such as cold and coughs. By examining the white blood cell count, the test provides essential insights into the body's immune response. An increased white blood cell count, specifically elevated neutrophils, can indicate an ongoing infection.

What are the five stages of flu?

In fall 2009 the emergency department of a clinic in Greece with increased patient visits due to influenza-like illness observed a particular pattern in the complete blood count (CBC) of these patients. In 90% of all patients with probable influenza, lymphopenia and/or monocytosis were present.

Several things can impact your test results. For example, they can vary due to the time of day your blood is drawn. If possible, try to schedule blood draws at the same time of day every time. If you're sick or have an infection, like a cold or flu, these can also affect your test results.

How to know viral infection from blood test?

The complete blood count (CBC) is one of the most common blood tests. It is often done as part of a routine checkup. This test measures many different parts of your blood, including red blood cells, white blood cells, and platelets.

How is flu diagnosed?

Full blood count — a viral infection may raise or reduce the white cell count; atypical lymphocytes may be reported. C-reactive protein (CRP) — this is elevated but usually less than 50 in a viral infection (CRP is a marker of inflammation anywhere in the body and is not a specific test for viral infections)
