The bacteria Chlamydia pneumoniae is spread by airborne droplets and infects the mucous membranes of the respiratory tract. These infections can be the cause of pharyngitis, laryngitis and sinusitis. A dry, hacking cough is the most common symptom of these infections. Not everyone who has mycoplasma and chlamydia in their nasopharynx gets sick - it depends on the body's resistance, but they can still infect others.

Chlamydia trachomatis is the most common cause of curable bacterial sexually transmitted infection (STI) worldwide. It manifests primarily as urethritis in males and endocervicitis in females.
Untreated chlamydial infection in man can cause epididymitis and proctitis. Though most women with Chlamydia infection are asymptomatic or have minimal symptoms, some develop salpingitis, endometritis, pelvic inflammatory disease (PID), ectopic pregnancy and tubal factor infertility. It is associated with an increased risk for the transmission or acquisition of HIV and is also attributed to be a risk factor for the development of cervical carcinoma.

Chlamydia, caused by the bacterium Chlamydia trachomatis, is one of the most prevalent sexually transmitted infections (STIs) worldwide. It primarily affects the genital tract, but can also impact the rectum, throat, and eyes. One of the key challenges in controlling Chlamydia is its often asymptomatic nature; a significant proportion of infected individuals exhibit no noticeable symptoms, thereby unknowingly facilitating its spread. When symptoms do occur, they can include genital discharge, burning during urination, lower abdominal pain, painful sexual intercourse for women, and testicular pain in men.

Chlamydophila pneumoniae is a type of bacteria that commonly causes respiratory infections, including bronchitis, sinusitis, and atypical pneumonia. In most cases, infections are mild and self-limiting, but in some individuals—especially older adults or those with weakened immune systems—it can contribute to more persistent or chronic respiratory conditions.
The IgG antibody test for Chlamydophila pneumoniae measures the body’s long-term immune response to this bacterium. IgG antibodies usually appear several weeks after infection and can remain in the bloodstream for months or even years. This means an elevated IgG result indicates past exposure or a previous infection.
A medium IgG result reflects a moderate level of antibodies, which may indicate:
A past infection that your body has responded to and is no longer fighting
A waning or borderline immune response, depending on timing and overall health
In some cases, cross-reactivity or residual antibodies from a remote infection
This result should be interpreted in the context of symptoms and additional lab findings.

Chloride, as measured in a random urine sample is essential for evaluating the body's electrolyte balance and acid-base status, as chloride is a major anion (negatively charged ion) found in the blood and urine. In this test, chloride levels are assessed alongside creatinine, a waste product produced by muscle metabolism, which serves as a reference to help interpret the chloride results more accurately. By comparing the amount of chloride to creatinine in the urine, healthcare providers can gain insights into the kidney's ability to filter and reabsorb essential minerals. This is particularly important in diagnosing and managing conditions related to electrolyte imbalances, dehydration, and kidney function.
Optimal range: 96 - 106 mEq/L , 96 - 106 mmol/L
Chloride is a molecule found in the body and belongs to the electrolyte group, indicating that it possesses an electrical charge. Electrolytes work to maintain the pH of our body fluids, help our cells to keep the amount of fluid inside and outside the cell balanced, and aid in the maintenance of proper blood volume / blood pressure. Tests for chloride, sodium, potassium, and bicarbonate are typically done together as part of an electrolyte panel, a basic metabolic panel, or a comprehensive metabolic panel. A healthcare professional may order an electrolyte panel when symptoms such as prolonged vomiting, diarrhea, weakness, and difficulty breathing are present. An electrolyte panel can also be used to determine the cause of a pH level in the blood that is too acidic or too alkaline. Additionally, electrolyte panels may be done routinely to monitor medications or diseases that are known to cause electrolyte imbalance. Chloride can be measured through blood or urine.
Optimal range: 110 - 250 mmol/24 hr
Chloride is the most abundant ion outside of cells. It is important for maintaining osmotic pressure, nerve cell function, and fluid balance. The urine chloride test is used primarily in cases of suspected metabolic alkalosis.

The Cholesterol Balance Score, a key marker on the Boston Heart Cholesterol Balance® test, provides a comprehensive assessment of an individual's cholesterol metabolism by evaluating the ratio of cholesterol production to absorption. This score is derived from the direct measurement of lathosterol and desmosterol (cholesterol production markers) and beta-sitosterol, campesterol, and cholestanol (cholesterol absorption markers). By offering insights into both production and absorption pathways, the Cholesterol Balance Score helps clinicians understand the underlying causes of dyslipidemia and tailor treatment strategies more effectively. This personalized approach can enhance the management of cardiovascular disease risk and improve patient outcomes by precisely targeting LDL-C lowering therapies.

Cholic acid (CA), Chenodeoxycholic acid (CDCA), Deoxycholic acid (DCA), Lithocholic acid (LCA) are the major bile acids related to gut microbiome.
Bile Acids are natural products of cholesterol synthesis that aid in the emulsification and absorption of dietary fats in the small intestine. Elevated total fecal bile acid is indicative of a diagnosis of bile acid malabsorption. Quantification of fecal bile acids aids in diagnosis for IBS and identification of patients with chronic diarrhea who may benefit from bile acid sequestrant therapy. There is a connection between the liver health, fecal bile acid concentrations, and gut microbiota composition. Bile acids have both direct antimicrobial effects on gut microbes and indirect effects through FXR-induced antimicrobial peptides.
Optimal range: 0 - 2.2 umol/L
Cholic acid is a primary bile acid synthesized in the liver from cholesterol. It plays a crucial role in the emulsification and absorption of dietary fats and fat-soluble vitamins in the small intestine. Cholic acid is also involved in regulating cholesterol levels and maintaining the integrity of the intestinal mucosa.

Choline is an essential nutrient that plays a foundational role in brain health, liver function, methylation, and neurotransmitter synthesis. It serves as both a structural building block for cell membranes and a biochemical precursor for several key molecules, including acetylcholine (a neurotransmitter critical for memory, focus, and muscle control) and betaine (trimethylglycine), a major methyl donor in the body.
On the Neurotransmitter XL panel, choline reflects the body’s capacity to maintain membrane integrity, neurotransmitter balance, and methylation efficiency. Adequate choline ensures optimal communication between neurons, healthy liver metabolism, and efficient detoxification through the methionine cycle, which depends on methyl donors for proper function.
Because the brain and liver are among the most metabolically active organs, choline status is often a key indicator of both cognitive performance and cellular energy balance.
Optimal range: 1.7 - 4 mg/g Creat.
Choline is an essential nutrient involved in various physiological processes, including cell membrane structure, lipid metabolism, and neurotransmitter synthesis. When measured in a urine sample as choline (mg/g creatinine), this biomarker can provide valuable insights into an individual's choline status and overall metabolic health. The measurement of choline in urine is often normalized to creatinine levels to account for variations in urine concentration, making the value more reliable and comparable across different samples and individuals. Interpreting choline levels in urine requires considering dietary intake, as choline is obtained from foods such as eggs, meat, fish, and certain vegetables.
Optimal range: 20 - 100 %
Choline is an essential nutrient that is part of cell membranes and is used by nerves to send impulses. Choline is known to be essential for mammals, and is essential for human cell growth. A dietary requirement for choline in humans has not been proven, although recent data on infants and dietary choline depletion in adults suggests that choline is an essential nutrient. Historically, choline is considered as a lipotrope and member of the B vitamin complex.
Choline has several distinct functions. First, choline serves as a source of one-carbon units (methyl groups) for biosynthesis of other compounds. Interactions with methionine, Vitamin B12, folate, ethanolamine, and betaine allow choline to partially replace, or be replaced by other constituents in one-carbon metabolism. Second, choline is a component of phosphatidyl choline, the major component of cell membranes. Lecithin is a commercial name for phospholipids containing 10-35% phosphatidyl choline. Phosphatidyl choline has interactions with cholesterol and lipoprotein metabolism.
