What is COVID-19 Neutralizing Antibody Test & Why do You Need to Get Tested?

COVID-19 Neutralizing Antibody Testing

“Quantitative detections of COVID-19 Neutralizing Antibodies in human serum,

plasma or whole blood”


What is the difference between COVID-19 Neutralizing Antibody and other COVID-19 antibodies? 1, 2

Unlike other COVID-19 antibodies, COVID-19 neutralizing antibodies prevent the interaction o f S protein RBD with ACE2 cell receptor, thus, preventing the entry of virus into the host.


Application of COVID-19 Neutralizing Antibody Detection³:



To check whether your body respond to vaccination and how much of this antibody is neutralizing

antibodies; assessment of potential antibody-associated immunity

Past – Infection

To identify individuals with past exposure

Blood Cancer & COVID-19

Blood Cancer & COVID-19

Most blood cancers, also called hematologic cancers, begin in the blood-forming tissues such as the bone marrow or in the cells of the immune system.1 Blood cancers occur when the normal blood cell development process is interrupted by uncontrolled abnormal blood cell growth, preventing functions such as fighting off infections or stopping serious bleeding.2


The three main types of blood cancers are2:

  1. Leukemia – a type of cancer that occurs in your blood and bone marrow due to rapid production of abnormal white blood cells. The high level of abnormal white blood cells are not able to fight off infections and cause impairment in the production of red blood cells and platelets in the bone marrow.


  1. Lymphoma – a type of blood cancer that affects the lymphatic system; which removes excess bodily fluids and produces immune cells. Lymphocytes are white blood cells that fight off infection. Abnormal lymphocytes turn into lymphoma cells that multiply and collect in your lymph nodes and other tissue which overtime, will impair your immune system.


  1. Myeloma – cancer of the plasma cells. Plasma cells are white blood cells that produce antibodies to fight off diseases and infections in your body. Myeloma cells prevent the normal production of antibodies causing the body’s immune system to be weakened and susceptible to infection.


Blood cancer & COVID-19

As COVID-19 emerged, patients with blood cancers are at increased risk of severe COVID-19 infection and high mortality rate due to their compromised immune system and inability to receive necessary care in time.3, 4, 5, 6 Medical practitioners have to assess whether treatment plans should begin on schedule or delayed until a certain time.5, 6  Studies have shown that patients with blood cancers are more susceptible to severe COVID-19 infection than patients with solid cancers or healthy people, likely due to the immunosuppressive nature of their disease and/or treatments. However, researchers sought to discover if immunosuppression caused patients with blood malignancies to have a decreased immune response to the COVID-19 vaccines that are now being provided around the world.

Pantai Premier Pathology COVID-19 Journey [May 2021]

Take a journey through PPP’s call of duty ensuring safety & peace of mind amidst the ongoing Pandemic. Let us not be complacent in this fight against Covid-19. Stay vigilant & stay safe!


In February 2020, Pantai Premier Pathology (PPP) received approval from the Ministry of Health as one of the 4 private labs in Malaysia to start the COVID-19 screening services. In March 2020, a total of 400 samples were run per day using the rtPCR method. These samples were received from various sites including IHH hospitals, GP clinics and corporate clients. In April 2020, PPP expanded its service offering that includes rtPCR and rapid PCR nationwide with an increase in the running capacity to 800 samples per day. A new service, RTK Antigen, was offered nationwide in May 2020, with increased running capacity to 3,500 per day. PPP has also offered support in running MOH samples when required at that time. A total YTD testing of 7.6% of the nationwide capacity at 207,396 tests was achieved in October 2020 with the launch of another service, RTK Antibody testing. In January 2021, PPP opened up another COVID-19 lab located at Pantai Hospital Ampang. After 12 months of providing COVID-19 screening service, PPP contributed to a total of 460,435 testing nationwide in February 2021. More COVID-19 screening labs were started at Gleneagles Medini, Johor Bahru and KLIA, Sepang in March 2021 with overall running capacity up to 8,000 tests per day. PPP has recorded the highest monthly total sample screened to date at 145,181 in one month as at May 2021.

Increase the Success Rate of IVF via PGS

Increase the Success Rate of IVF via PGS


In Vitro Fertilization (IVF) is an assisted reproductive technology (ART) to achieve pregnancy, where the process of fertilization is manually performed in a laboratory dish by combining extracted eggs and retrieved sperms. Once the fertilized eggs have multiplied, the embryos are then transferred to the uterus for a pregnancy to begin.1, 2, 3 This procedure is commonly conducted in couples who have difficulty in achieving pregnancy through unprotected regular intercource.2

Figure 1: The process of In Vitro Fertilisation (IVF).4


Who needs IVF treatment?

IVF can be used to treat infertility in the following cases1:

  • Unexplained infertility
  • Women with ovulation disorders; premature ovarian failure, uterine fibroids
  • Blocked or damaged fallopian tubes
  • Male factor infertility; reduced sperm count or motility
  • Individuals with genetic disorder


What is Preimplantation Genetic Screening (PGS)?

PGS is a specialised testing to screen whether cells from a cultured embryo contain any chromosomal abnormalities or balance number of chromosomes prior to implantation. PGS is highly recommended for patients with history of repeated unexplained miscarriages, recurrent IVF failures or couples with known abnormality in their chromosomal who worry passing it on to their offspring.

Common chromosomal abnormality PGS screens for are:

  1. Down Syndrome
  2. Patau Syndrome
  3. Edwards Syndrome
  4. Sex chromosomes abnormality

The process of PGS requires a small number of cells from the cultured embryos typically at day 5 (blastocyst stage) and cells are screened for normal number of chromosomes which is 46 (23 chromosomes inherited from each parents). If all chromosomes are intact with no abnormalities observed (called euploidy) then the embryo is suitable for implantation.6, 7, 10, 11, 12 Your fertility doctors will consult of the best embryos to implant in order to yield a successful pregnancy.

End TB, Save lives

End TB, Save lives

Persistent cough that lasts for more than 3 weeks with the presence of blood or mucus is a warning sign for a deadliest infectious disease known as Tuberculosis (TB).1, 2 TB bacteria spreads through air when someone with TB disease talks, coughs or sneezes.3 Individuals at risk for TB are those living with HIV and have close contact with TB patients and other at-risk groups such as patients undergoing dialysis, anti-TNF (tumor necrosis factor) treatment and patients preparing for an organ transplant.3 These individuals have weakened immune system which makes them vulnerable to getting infected.

Individuals with latent TB infection have TB bacteria in their bodies but are not sick, do not display symptoms or cannot spread the bacteria to others because the bacteria are not active. However, these individuals may develop TB disease in the future, hence, they are often prescribed treatment to prevent from developing TB disease. Whereas, individuals with TB disease are sick from TB bacteria that are active, multiplying and destroying tissues in their body. These individuals usually display symptoms of the TB disease and are able to spread the bacteria to others.6

TB is a preventable and curable disease, however, a person with TB can die if they do not get treatment on time.5, 6 Most TB cases are reported to progress from latent TB infection (LTBI) rather than local transmission, especially in those whose immune systems are weakened. Hence, the transmission of the infectious TB can be prevented through prompt case finding and treatment of LTBI as a crucial strategy to achieve the elimination of TB.7, 8, 9
