What is Candida?

Candida (Candida Albicans)

  • Not a female-specific issue
  • A kind of yeast, a fungus and a microorganism in every human body
  • Lives mainly in the mucous membranes of the mouth, intestinal and digestive tract and vagina.
  • Candida is normally kept under control by good health and probiotics, live symbiotically within us.

Why will Candida overgrow?

When there are factors promoting the Candida overgrowth and the body is immunocompromised, Candida overgrow is very likely to appear. Some risk factors are listed below:

Isn’t Candida just a female or skin issue?

Yeast infections are mostly occurred on the body surface or locally at vagina. These infections often can be cured by simple treatment.
Typical swab test can only evaluate localized Candida infection.
Yet Candida presents deep inside our body, plus the use of antibiotics and other lifestyle factors encourage Candida to grow. There is a need to take a look on how Candida affects us systemically.

Candida overgrowth – Feeling Unwell All Over

  • The manifestations of Candida overgrowth are hard to detect as these symptoms tend to overlap with other illnesses, making Candida overgrowth easily ignored.
Skin Digestive System Cognitive & Psychological Head & Neck Other
Acnes, Skin rashes, Onychomycosis Irritable Bowel Syndrome(IBS), Diarrhea, Constipation, Bloating Chronic fatigues, Anxiety, Depression, Attention deficit, Irritability, Premenstrual tension, Attention deficit Oral thrush, Headaches, Recurrent sore throats, Nasal congestion or Ear infection Vaginitis, Urinary tract infections, Athlete’s foot, Heart palpitation, Delayed food allergy, Sexual dysfunction, Sweet craving

How Candida overgrowth affect our body?

Toxins excreted by Candida

  • Metabolite produced by Candida is toxic to our system: Destroy cell membranes and enzymes
    • Red blood cell → Blood flow in capillaries and oxygen carrying ability impede
    • White blood cell → Reduce ability to fight against infection
    • Thyroid hormone → Weaken the metabolic capacity that led to body temperature drops, unable to tolerate cold and lead to fatigue
    • Enzymes → Slow down body functions

Influence of Candida overgrowth and colonization:Leaky Gut

  • Gut is a major place for Candida to grow, the strains will grow and penetrate intestinal mucosa, making it more permeable.
  • “Leaky Gut” is formed when the wrong molecules (i.e. Large protein molecules, toxins and food allergens) pass though the mucous membrane and absorbed into bloodstream, it will lead to digestive problems and food sensitivities.

If you experience symptoms similar to Candida overgrowth, you could use the questionnaire, to evaluate the possibility of having Candida overgrown, and use our test to root the source of the health problem!


Reliable Technology that We Trust, Duplicate Runs for Ultimate Precision

  • Fully automated robotic systems for our ELISA platform
  • Duplicate runs of each sample for ultimate precision
  • Superior specimen integrity with finger prick whole blood specimens
the first antibody formed after primary exposure
a present or early infection
the antibody formed after secondary exposure
a past, active or prolonged infection
found in mucous secretions for local (mucosal)
an infection of the mucous membrane
Candida Antigens  the presence of Candida infection, specifically for immunodeficient individuals

Technology Competency

Our ELISA technology measures IgG, IgA, IgM antibodies and Candida antigens from your blood precisely.


– A swab does not differentiate between a candida infection and a colony of normally occurring vaginal Candida. A vaginal swab test will only indicate what is going on locally, but not systemically.
– If the patients have used a vaginal pessary or a douche and the area is sanitized to a degree, a swab will return a false negative reading – simply on account of numbers that register too low for detection.





Not only a Female Issue

Jason L. & Beth L., Hong Kong
“Originally I consulted HK BioTek for my wife, realized that it is not a female issue, I got myself tested as well. We were both found to be positive and start a Candida diet and take probiotics. Many of those ‘small’ symptoms are gone, and we have become more energetic than ever! Glad that I have come across your website about this test.”

Thanks! I have lost some weight!

Kristy Chen, Hong Kong/ Beijing, China
“I do not mean to be dramatic but I feel better today than I have in the last few years. I read a book about yeast infection few years and that book made me suspect that I may be over-prescribed antibiotics when I lived in Hong Kong and Beijing. My result was positive- I switched to a diet to combat candida and took probiotics. I have lost over 10 pounds when following the diet – by cutting simple sugars. Thanks that I have read that book and took this test.”

Insomnia & Fatigue

Functional Medicine Practitioner, Hong Kong
“After testing and followed the treatment plan based on the result, I have noticed significant improvement on the itchy skin and breakouts from my patient. I am very happy with the testing service from HK BioTek, and intend on continuing making their tests as a part of my treatments for sure.”


Why Candida?

1. What are the benefits of the Candida test?

  • Semi-quantitative analysis of IgG, IgM, IgA and Candida antigens through ELISA procedure.
  • Only a few drops of blood required
  • Analysis completed in the U.S.
  • Comprehensive supporting information in client information sheets

2. Aren’t Candida yeast infections only a female problem?

This is a common misconception. While the vaginal Candida infection is very common in women, that’s not the only form of yeast infection. Other very common forms of Candida infections include athlete’s foot, ringworm, oral thrush, jock itch, and other fungal skin irritations. It can possibly be the cause of feeling sick all over in men, women and children.

3. Is the Candida screening suitable for all ages? 

Adults and children can take the test. Candida can be found in human bodies shortly after birth and persists throughout the life. Research studies indicate that approximately 90% of all infants at six months of age carry Candida in their bodies while the prevalence is almost 100% in adults. In general, infants after 6 months start to produce their own antibodies. Thus, kids age after 6 months can take test to find out an overgrowth exists.



1. How do I go about the Candida Screening?

You could:

  • Make an appointment to complete the blood collection process in sampling outlet

Office Hours: 10am-7pm (Mon-Fri); 9am-5pm (Sat); Closed on Sun & Public Holidays

We will send your sample direct to the US lab for testing. You will receive the results within 10 – 20 days.

2. How much blood is needed for the Candida screening?

5ml blood by blood drawing.

3. Could we know more about the specificity and accuracy of our test ?

  • Precision is greater than 85%!
  • Utilizes the fully automated robotic ELISA system: Stringent biochemical process detect antibodies in the blood, which interprets your immune system’s response to Candida.
  • Assurance of quality and reliability as all tests are completed under US BioTek Laboratories’ facilities.
  • Each sample is run twice to ensure consistent results.
  • Laboratory approved by CLIA (US Clinical Laboratory Improvement Amendments) accredited by COLA (US Commission on Office Laboratory Accreditation), and licensed by the State of Washington for performing testing worldwide.



1. Do I need a doctor’s prescription to have the Candida test done?

Any individual can order any tests for his or her health information purpose. A doctor’s prescription is not required.

2. Can I have this test done if I am taking Chinese or Western medicine?

The major concern is steroidal drugs, e.g. cortisone, because it can suppress the immune system, and thus may reduce the antibodies present, causing a “false negative” result. Thus it is advisable to avoid taking the steroidal drug for at least 3 weeks before taking the test. Tropical steroid is not part of the concerns.



1. What information will the Candida screening report provide?

Candida screening result would be shown as values of different analytes and reference values
IgM: a present or early infection.
IgG: a past, active or prolonged infection.
IgA: an infection of the mucous membrane.
Candida antigen: the presence of Candida infection, specifically for immunodeficient individuals

2. What Shall I do to control my Candida overgrowth?

Naturally controlling Candida yeast infection takes time and patience. If you have an acute yeast attack, like a vaginal infection or athlete’s foot, you can visit medical doctors or find over-the-counter antifungal creams and drugs. If you have a Candida overgrowth that is affecting you chronically, you shall consider following an anti-Candida diet, modifying your lifestyle, and taking antifungals and probiotics. You may also consider taking some additional herbal supplements to strengthen your immune system.

After you get your test results, you will be provided with some guidelines on your lifestyle, diet and supplementation to control you Candida overgrowth.
