> How quickly thyroid blood tests, ultrasound and biopsy results are ready, and what can make results take longer.

Waiting for results can be stressful. Most thyroid tests are quick, but the time to a final answer depends on which test you had and where it was processed.
This page gives a realistic timeline for the main thyroid tests.

## Blood tests

Thyroid blood tests — TSH, free T4, free T3 and antibodies — are usually reported within one to three working days. Many laboratories offer same-day or next-day results.
Specialised tests such as TRAb or thyroglobulin may take a little longer because they are run less frequently.

## Ultrasound

An ultrasound report is often available the same day or within a day or two, depending on the imaging centre. The scan itself takes only minutes, but the images must be reviewed and reported by a radiologist.

## Biopsy (FNAC)

Cytology results from a thyroid biopsy usually take a few days, as the sample must be processed and examined by a pathologist. Some centres offer faster reporting for urgent cases.
If the sample is not adequate, a repeat biopsy may be needed, which extends the timeline.

## What can delay results

Weekends and public holidays, referral delays, and requests for additional tests can all add time. If you are waiting, it is reasonable to contact the laboratory or your clinician to check progress.
