IDO (indoleamine 2,3-dioxygenase) activity reflects the rate at which the amino acid tryptophan is converted into kynurenine.  
This pathway is regulated by immune and inflammatory signals, particularly cytokines such as interferon-γ.  
Increased IDO activity (low tryptophan/kynurenine ratio) may indicate immune activation, chronic inflammation, or oxidative stress.  
Balanced IDO activity suggests normal immune regulation and sufficient tryptophan availability for serotonin and melatonin synthesis.

IDO Activity (Tryptophan/Kynurenine ratio)

Blood group A has A antigens on the surface of red blood cells and anti-B antibodies in the plasma. Individuals with this blood group can donate blood to people with blood group A or AB. They can receive blood from group A or O donors. Group A is one of the most common blood types worldwide. Proper matching is essential to avoid transfusion reactions.

Blood Type A

Influenza B is a type of influenza virus that contributes to seasonal flu outbreaks, primarily affecting humans.

Free chlorine is a measure of the chlorine available in water for disinfection. It is a strong oxidizing agent that exists primarily as hypochlorous acid (HOCl) or hypochlorite ion (OCl⁻), depending on the water’s pH. Free chlorine plays a key role in killing harmful bacteria and viruses, helping to ensure water safety, but must be carefully controlled due to its high reactivity.

Free Chlorine

Nitrates (NO₃⁻) and nitrites (NO₂⁻) are nitrogen-oxygen compounds commonly found in water, either from natural sources or as a result of agricultural runoff and industrial activity. Both serve as indicators of water quality and, at elevated levels, can pose health risks, especially to vulnerable populations.

Nitrates and Nitrites

Fentanyl is a synthetic opioid that is significantly more potent than morphine. It is mainly used to manage severe or chronic pain and is available in forms such as patches, lozenges, and injections. Due to its high potency, fentanyl carries a strong risk of addiction and overdose, even at low doses. It is also illegally manufactured and sometimes mixed with other drugs, increasing the risk of accidental overdoses.

Fentanyl

Marijuana is a substance derived from the Cannabis sativa plant and contains THC (tetrahydrocannabinol), a compound known for its psychoactive effects. It is used recreationally for its calming and euphoric effects, and medically for managing pain, nausea, and symptoms of chronic conditions. Its legal status varies across regions, with increasing acceptance for medical use.

Marijuana

Cocaine is a powerful illegal stimulant derived from the coca plant. It is commonly snorted, inhaled, or injected, producing short-lived intense euphoria, increased energy, and heightened alertness. Cocaine use carries serious health risks including heart attacks, strokes, and addiction. It is known for its high potential for abuse and is classified as a Schedule II drug in the United States.

Pathogenic bacteria often enter water sources through sewage, animal waste, or natural environments, making proper water management essential to prevent illness.

Bacteria

Gamma-Hydroxybutyric acid (GHB) is a naturally occurring substance and a central nervous system depressant. Although it is found in small amounts in the human body, it is more commonly known for its illegal use because of its sedative and euphoric effects. At higher doses, GHB can cause drowsiness, dizziness, nausea, unconsciousness, memory loss, and potentially life-threatening effects. Its narrow safety margin makes the risk of overdose high. GHB is sometimes referred to as a “date rape drug” because it can be added to drinks without any noticeable taste, smell, or color.

GHB (Gamma-Hydroxybutyric Acid)

Oxycodone is a powerful opioid medication used to alleviate moderate to severe pain. It works by attaching to opioid receptors in the brain and spinal cord, lessening the sensation of pain and its emotional effects. While effective for managing pain, oxycodone carries a high risk of dependence, addiction, and misuse.

Oxycodone

Buprenorphine is a medication primarily used to treat opioid addiction and, to a lesser extent, manage chronic pain. It functions as a partial opioid agonist, producing effects similar to opioids but with a lower risk of dependence and abuse compared to full opioid agonists like morphine or heroin. Buprenorphine is commonly used in medication-assisted treatment (MAT) to help reduce withdrawal symptoms and cravings.

Buprenorphine

Benzodiazepines are a class of psychoactive drugs that work by enhancing the neurotransmitter GABA in the brain, producing a calming effect. They are commonly prescribed to treat anxiety, insomnia, seizures, and muscle spasms. Popular benzodiazepines include Valium (diazepam), Xanax (alprazolam), and Ativan (lorazepam). While effective, they carry risks of dependence and withdrawal, especially with long-term use.

Benzodiazepines

Spermine is a polyamine derived from spermidine that plays a crucial role in stabilizing DNA, RNA, and cellular membranes. It contributes to antioxidant defense, inflammation regulation, and the control of cellular aging. Elevated levels can occur during periods of high metabolic or regenerative activity, while low levels may indicate reduced polyamine synthesis or increased cellular stress. Balanced spermine levels support optimal cellular integrity and protection against premature aging.

Spermine

Copper in water refers to the presence of the metallic element copper (Cu) dissolved or suspended in water. Copper can enter water sources naturally through geological processes or from human activities such as corrosion of copper pipes, industrial discharges, and mining operations. Monitoring copper levels is important for assessing water quality and potential impacts on human health.

Copper

Sulfate in water refers to the concentration of sulfate ions (SO₄²⁻) dissolved in the water. Sulfate is a naturally occurring anion found in many water sources and can also come from industrial activities, mining, and agricultural runoff. It is an important water quality parameter that affects both water characteristics and potential environmental impacts.

Sulfate

Spermidine is a naturally occurring polyamine that plays a role in cellular growth, repair, and protection. It supports autophagy — the body’s natural process of removing damaged cells — and contributes to mitochondrial function and longevity pathways. Higher levels are often linked to improved cellular renewal and resilience against oxidative stress. Low levels may indicate decreased cell turnover, nutritional deficiencies, or increased oxidative stress.

Spermidine

Chloride is an anion (negatively charged ion) made up of chlorine atoms and is a naturally occurring component in many water sources. It originates from the dissolution of salts containing chloride, such as sodium chloride and calcium chloride, in the Earth's crust. Chloride is commonly found in both freshwater and saltwater, and its concentration can vary depending on geological and environmental factors.

The Monkeypox virus A29L antigen is a surface protein linked to the monkeypox virus (Mpox), a zoonotic virus that can spread from animals to humans and between people. Detecting the A29L antigen in a sample signals an active infection, as antigens are usually present during the early symptomatic stage of the illness.

Monkeypox virus A29L antigen

Blood group B has B antigens on red blood cells and anti-A antibodies in the plasma. Individuals with this blood type can donate blood to those with blood group B or AB. They can receive blood from donors with blood group B or O. Blood group B is less common in certain areas. Compatibility is essential for safe transfusions.

Blood Type B

Blood group AB has both A and B antigens on red blood cells and no anti-A or anti-B antibodies in the plasma. It is known as the universal recipient for red blood cell transfusions because individuals with this group can receive blood from all other groups. However, they can only donate blood to others with blood group AB. AB is the rarest of the four main blood groups. It is important to consider both ABO and Rh compatibility in transfusions.

Blood Group AB

Blood group O has neither A nor B antigens on red blood cells but contains both anti-A and anti-B antibodies in the plasma. Individuals with this blood type can donate red blood cells to anyone (universal donor) but can only receive blood from group O. Blood group O is the most common blood type in many populations. Because it lacks A and B antigens, it plays a crucial role in emergency transfusions.

Blood Group O

The home test was straightforward with easy to follow instructions. The test result was detailed and clear in its presentation. Also had the opportunity to ask questions about the test result.

We looked at a lot of companies offering the same services but made the decision to go forward with get tested because the labs are based here in the USA. The process has been very straight forward.

There are other providers out there, I have tried 3. Gettested was the fastest and the customer service was the best. I even received my test on the day of purchase delivered by a motorbike courier.

Absolutely perfect, results came after few days and finally after a lots of times visited GP, we finally know why my son has eczema - he is allergy to carrot. Thanks a lot.

I found them to be professional and not too long a wait for results. Helpful with any after questions. Will be using them again if need be. I highly recommend them.

Nitrates and nitrites can contaminate drinking water sources, particularly groundwater, and pose health risks, especially to infants and pregnant women. Monitoring these substances helps ensure water safety.
</div>

Why test nitrates and nitrites?

<div id="symtm-2" class="symtm-text">
 Nitrates and nitrites themselves do not significantly affect the taste, odor, or color of drinking water at typical concentrations. However, their presence can lead to the formation of nitrosamines, which can have a bitter taste and are potentially carcinogenic. Additionally, high nitrate levels can indicate contamination from agricultural runoff or septic systems, affecting water quality.
</div>

How does nitrates and nitrites affect the taste and quality of drinking water?

<div id="symtm-3" class="symtm-text">
 High levels of nitrates and nitrites in drinking water are of concern because they can lead to health issues, particularly in infants and pregnant women. Nitrate exposure can lead to methemoglobinemia or &ldquo;blue baby syndrome,&rdquo; a condition where the blood&rsquo;s ability to carry oxygen is impaired, potentially causing serious health problems. Nitrites can also react with other compounds in the body to form potentially harmful nitrosamines, which are carcinogenic
</div>

What are the health effects of exposure to high levels of nitrates and nitrites in drinking water?

<div id="symtm-4" class="symtm-text">
 Common sources of nitrates and nitrites in water include agricultural runoff, especially from excessive fertilizer use, and septic system leakage. Industrial discharges and contamination from improperly managed livestock operations can also contribute to elevated levels of these compounds in water sources. Natural processes, such as the breakdown of organic matter, can release nitrates and nitrites into the water as well.
