What tests will I have?

Tests may include:

• blood tests

• if appropriate, an exercise tolerance test suited to your ability (for example a one-minute sit-to-stand test)

• measuring your lying and standing blood pressure and heart rate

• if you haven't already had one, a chest X-ray by 12 weeks if you still have breathing difficulties.

Symptoms of postural tachycardia syndrome (PoTS) have been reported in people with long COVID. PoTS is an abnormal increase in heart rate that happens after standing up. It is associated with symptoms that include lightheadedness, palpitations and fatigue. These can sometimes be misdiagnosed as anxiety or panic attacks, and should be investigated.

If you have mental health symptoms such as mild anxiety or mild depression, you may be referred:

• for psychological therapies, or

• to a liaison psychiatry service if you have more complex physical and mental health needs.

If your healthcare professional thinks your symptoms are not related to COVID-19 and may be due to another condition, you will be offered other appropriate tests. You may also be referred to a specialist in that condition.
