Man’s warning to check closely for faint second lines on their Covid RAT tests

Urgent warning to double check Covid rapid tests after man’s positive result was BARELY visible – and how an iPhone camera can help you spot it

  • A man has warned to be aware of faint positives on Covid-19 home testing kits 
  • An image of the RAT test shows the second red line was barely visible 
  • After carefully inspecting the result, he got tested and was confirmed positive
  • A woman also revealed how to use photo editing tools to help see faint lines

A man has warned Australians to double-check for second lines on Covid-19 rapid antigen tests (RAT) after his own positive result was extremely faint.

The anonymous Victorian man, who runs the online community ‘Covid Pete’, shared an image of his test result on Facebook with the second red line barely visible.

He then visited a Covid-19 PCR testing clinic which later confirmed he was positive.

‘When I started having symptoms and others who were around me starting testing positive with their RAT test, I decided to do mine. As you can see the second line of mine is very faint,’ the caption read.

‘You must take that second faint line as a positive test!!! It was confirmed a few days later that I was positive via PCR.’

He warned others to be ‘aware and cautious of your surroundings’ and to get PCR tested even if the faintest line is noticed on RAT home kits.

How do rapid antigen tests work? 

Rapid antigen tests use a nasal swab or saliva sample to test for the presence of the virus that causes COVID-19.

You can easily perform the test at home and should get your results within 20 minutes.

The Therapeutic Goods Administration (TGA) has approved several rapid antigen self-tests for use in Australia. 

You should only perform a rapid antigen self-test if you have symptoms of Covid-19. If positive, a PCR should be taken to confirm the result. 

RAT tests can be purchased from supermarkets, pharmacies and health stores around the country.


A woman has also explained how to use editing tools on an iPhone to identify faint positives.

After taking a photo of the test, she suggested increasing the black point and contrast to 100 per cent

‘You can also invert the colours and this will often help you see faint lines,’ she wrote. 

Prime Minister Scott Morrison is set to make a decision on subsidising RATs for Australians on low incomes.   

The plan, set for discussion at National Cabinet on Wednesday, will see welfare recipients and pensioners get cash payments for up to five rapid tests, or even more if states also put money on the table.

They would need to meet eligibility requirements to qualify for the subsidy.

The Prime Minister may also announce that the Federal Government will provide millions of free RAT kits to be handed out at state and territory testing centres.

The national cabinet is meeting for the first time this year to discuss community concerns around access to the kits, which have been difficult to source and have risen steeply in price. 

What should I do if the RAT test is positive?

1. Isolate at home for at least 7 days from the day you had your PCR test. If you have symptoms at Day 6, have another PCR test at a walk in or drive through testing clinic. 

2. If test is positive you must stay at home until symptoms are gone or have a negative PCR test. If you have symptoms at Day 12, have a PCR or RAT self-test. 

3. Notify your household, school or employer that you have COVID-19. 

4. If you have no symptoms at Day 7, you can return to normal living and leave your home. You do not need a further test. 

Wear a mask when leaving the home and avoid visiting high-risk settings for at least 7 days following negative test or end of symptoms.


Infectious diseases expert Professor Robert Booy said the proposed measures would help alleviate pressure on testing clinics, but they should be made free for everyone not just those on low incomes.

‘We can’t have a system that doesn’t work, we need to be able to test people by PCR if they have got symptoms or if they are a very close contact,’ he told the Nine Network on Wednesday.

‘We need to do something and rapid antigen tests are the solution.’

The consumer watchdog on Tuesday acknowledged community concerns some retailers were price gouging on the tests due to their scarcity and asked the community to report pricing anomalies.

Australian Competition and Consumer Commission chair Rod Sims warned the authority would ‘name and shame’ retailers doing the wrong thing.

Health Services Union NSW secretary Gerard Hayes has heard of some retailers selling the rapid tests for $100, and urged for free tests.  

Covid cases in NSW spiked to 35,054 while Victoria recorded 17,636 new infections overnight – but ICU admissions in both states remain steady.

Wednesday’s numbers in NSW are the highest daily total recorded for any Australian state since the beginning of the pandemic – and are a large jump from the 23,131 infections announced on Tuesday.

The number of people in hospital has risen to 1491, from 1344 reported on Tuesday. Of those, 119 are in intensive care units, an increase of 14 in 24 hours.  

While ICU numbers are rising, the tally is short of the peak of 244 seen in September.

Victoria’s hospitalisations are at 591, a jump from 516 on Tuesday, with ICU rates dropping by three to 53.

Eight more people in NSW lost their lives with the virus while Victoria had 11 deaths.
