COVID- 19 Tests – What Do You Need To Know?

COVID- 19 tests – What do you need to know?

Author: Dr. Rakesh Choudhary MBBS, MS, FRCS UK, FRCS Orth UK, MChOrth UK.

So many of us think it is not their job to learn about COVID-19 tests and this should be left for the experts and governments to decide about these tests. But I strongly suggest the public must have a basic understanding of these tests which they may have to have themselves.

Basically there are two types of tests, one which can detect the virus in the body and the other one which tells if the person had the previous infection.

Virus test

The virus test detects an active infection. It detects the genetic material (RNA) of the virus during an active infection. It is also called a PCR (polymerase chain reaction) test or nucleic acid test and is sometimes inaccurately called an antigen test.

A swab is taken from deep in the back of your throat and deep in the nose. The swab should go deep up to 7-8 cm and is generally uncomfortable for the patient. Swabbing patients using the correct technique is paramount in ensuring an accurate result. By simply swabbing the inside of the nasal passage is not deep enough to verify that the virus is present.

What does virus testing tell you?

This test tells us if a patient is actively infected with the COVID-19 virus. Virus testing is used mainly for the diagnosis of COVID-19.

When should it be done?

The virus test works best during the first seven days of symptoms.

The coronavirus can be detected in swabs even before symptoms of illness first appear . This is why people can be infectious for a few days before the onset of symptoms, which usually appear about 5 days after the virus infects. Some people have no symptoms throughout their infection but are positive on the virus test and infectious to others. After a few days of illness, the concentration of the virus falls (as seen in swab samples) and the symptoms of the illness usually recede.

Accuracy of the test

In a person with COVID-19, the test is less likely to give a positive result late in the course of infection once the virus has been cleared by the immune system, or if an inadequate sample is taken from the nose or throat. There are concerns that the rate of ‘false negative’ test results could be as high as 30% and a significant number of people are wrongly being told they do not have the virus.

Antibody test

Antibody tests check your blood by looking for antibodies, which may tell you if you had a past infection with the virus that causes COVID-19. Antibodies are protein structures that are produced by the immune system in response to certain infections. The antibody can help fight off infections and can provide protection against getting that disease again (immunity). Antibodies are disease-specific. For example, measles antibodies will protect you from getting measles if you are exposed to it.

The antibody test detects the presence of antibodies as a marker of past infection. The antibody test (blood test) will only detect infections after the immune system has produced antibodies that recognize the virus. This happens approximately 7–10 days after symptoms develop.

Tests carried out a week after a patient develops symptoms will detect only 30% of people who had COVID-19 infection. Accuracy increases to 72% at two weeks and to 94% in the third week. Some people may take even longer to develop antibodies, and some people who are infected may not ever develop antibodies.

Interpretation of the antibody test is complex for non-medical people. Basically having antibodies to the virus that causes COVID-19 may provide protection from getting infected with the virus again. If it does, we do not know how much protection the antibodies may provide or how long this protection may last.

Only Health-Based Rewards: Why Wellness-Focused Incentives Drive Healthier Workplaces

Corporate rewards have traditionally focused on monetary incentives, gift cards or generic perks. However, organisations are increasingly realising that such rewards offer only short-lived motivation. Only health-based rewards, such as massages, gym bags and fitness trackers, represent a more effective approach to corporate wellness by reinforcing healthy behaviours that deliver long-term benefits.

In India, where lifestyle diseases are rising rapidly among working professionals, aligning rewards with health outcomes is no longer optional.

What Are Health-Based Rewards?

Health-based rewards are incentives designed specifically to improve or support employee wellbeing.

They focus on:

physical health
mental wellbeing
preventive care
recovery and stress relief

Unlike cash incentives, they encourage repeated healthy actions.

Why Traditional Rewards Fall Short

Cash rewards and generic gifts:

provide temporary satisfaction
do not influence daily habits
fail to support long-term wellbeing

Behavioural studies show that incentives disconnected from health goals have limited preventive impact.

The Case for Only Health-Based Rewards

Health-based rewards directly reinforce behaviours such as:

regular physical activity
stress management
recovery and self-care
preventive health participation

WHO workplace health guidelines emphasise incentives that promote sustained behaviour change.

Types of Effective Health-Based Rewards

Massages and Recovery Therapies

Massage therapy:

reduces muscle tension
lowers stress hormones
improves circulation

Monthly or quarterly massage rewards support physical and mental recovery.

Gym Bags and Fitness Gear

Practical fitness accessories:

encourage regular workouts
reduce barriers to exercise
promote active lifestyles

Visible gear reinforces identity as a health-conscious individual.

Fitness Trackers

Fitness trackers:

track steps, activity and sleep
create accountability
encourage daily movement

Data-driven feedback increases participation and motivation.

Psychological Impact of Health-Based Rewards

Health rewards create:

intrinsic motivation
positive habit reinforcement
long-term lifestyle shifts

Unlike cash, they associate rewards with self-care rather than consumption.

Impact on Employee Health Outcomes

Regular participation in wellness incentives leads to:

improved physical activity levels
reduced stress
better sleep patterns

ICMR data links activity-based interventions with lower lifestyle disease risk.

Benefits for Employers

Reduced Healthcare Costs

Preventive health rewards reduce chronic disease burden over time.

Improved Productivity

Healthy employees demonstrate:

better focus
fewer sick days
higher energy levels

Stronger Wellness Culture

Health-first rewards signal genuine organisational commitment.

EY-FICCI reports show preventive wellness programs deliver measurable ROI within 12–18 months.

Why Health-Based Rewards Work Better in India

Indian workplaces face:

long working hours
sedentary routines
high stress levels

Health rewards directly address these risks rather than ignoring them.

Aligning Rewards With Preventive Healthcare

Health-based rewards complement:

health screenings
fitness challenges
mental wellbeing programs

This integrated approach strengthens outcomes.

Avoiding Pitfalls in Reward Design

Effective programs:

avoid one-size-fits-all rewards
offer choice within health categories
ensure inclusivity

Poorly designed incentives reduce engagement.

Measuring Success of Health-Based Rewards

Success indicators include:

participation rates
health screening uptake
employee feedback
reduced absenteeism

Data-driven evaluation improves program effectiveness.

Long-Term Behaviour Change

Sustained wellness improvement requires:

consistency
reinforcement
meaningful incentives

Health-based rewards support gradual but lasting change.

Role of Leadership Support

Leadership participation:

increases credibility
boosts engagement
normalises wellness culture

When leaders embrace health rewards, employees follow.

Health-Based Rewards and Mental Wellbeing

Rewards such as massages and fitness trackers:

reduce burnout
improve mood
enhance resilience

Creating a Preventive Wellness Ecosystem

Only health-based rewards work best when combined with:

education
screenings
access to care

WHO emphasises integrated wellness ecosystems for maximum impact.

Conclusion

Only health-based rewards represent a strategic shift from short-term perks to long-term wellbeing investments. Incentives such as massages, gym bags and fitness trackers actively promote healthy habits, reduce lifestyle disease risk and strengthen workplace wellness culture. By aligning rewards with preventive health goals, organisations create meaningful engagement, healthier employees and sustainable productivity gains. Health-focused incentives are not just rewards—they are tools for lasting wellbeing.
