N-Valerylglycine

Organic Acids, Comprehensive, Quantitative, Quest Diagnostics

Optimal range:   0 - 0 mmol/mol creatinine

N-Valerylglycine (also known as N-Pentanoylglycine) is an acyl derivative of Glycine. The presence of N-Valerylglycine (among other metabolites) in urine is used in medicine to diagnose inborn errors of metabolism (such as mitochondrial fatty acid b-oxidation defects) through the use of liquid chromatography coupled with tandem mass spectrometry.

Na/K

Profile 1, Trace Elements (Hair), Trace Elements

Optimal range:   1.4 - 3.4 Ratio

The Sodium to Potassium ratio (Na/K) is a crucial indicator of stress on the adrenal glands, and its proper regulation is essential for maintaining overall health. Aldosterone and cortisol play key roles in controlling sodium and potassium levels in the body, influencing blood pressure and stress response. Proper management of this ratio is vital for maintaining physiological balance and well-being.

Optimal range:   1.2 - 4.8 Ratio

The Na+/K+ (sodium-to-potassium) ratio is a critical marker of mineral balance and is closely linked to kidney and adrenal function. Sodium and potassium are essential electrolytes involved in blood pressure regulation, muscle contraction, and cell-to-cell communication, and their balance significantly impacts overall health.

Na/Mg

Hair

Profile 1, Trace Elements (Hair), Trace Elements

Optimal range:   2 - 6 Ratio

The Na/Mg ratio in a Profile 1, Trace Elements (Hair) panel is crucial for assessing health and nutrition. This ratio, comparing Sodium (Na) and Magnesium (Mg), helps identify imbalances that may indicate conditions like hypertension or adrenal insufficiency. Sodium is essential for fluid balance and nerve function, while Magnesium is key for enzymatic reactions and muscle function. A balanced Na/Mg ratio is vital for cellular health and metabolic efficiency. Deviations can guide dietary and lifestyle adjustments, with significant implications in nutritional therapy and holistic health care. This analysis provides non-invasive, long-term metabolic insights, aiding in tailored health strategies.

NASEM Recommended Summation

Blood

PFAS (FOREVER CHEMICALS) 9 PANEL, Quest Diagnostics

Optimal range:   0 - 2 ng/mL

The NASEM Recommended Summation is a key component in interpreting the results of the PFAS (Forever Chemicals) 9 Panel by Quest Diagnostics. It represents a cumulative measure of the levels of the 9 PFAS chemicals tested in the blood. This summation provides an overall indication of a person’s exposure to PFAS, which are known for their persistence in the environment and human body due to their strong carbon-fluorine bonds.

If the result of the NASEM Recommended Summation is categorized as "intermediate," it indicates that the levels of PFAS in your blood are neither low nor high, but fall somewhere in between. This means that your overall exposure to PFAS, as measured by the test, is moderate.

What Does an "Intermediate" Result Mean?

An "intermediate" result suggests that while you may not have a very high level of PFAS in your body, there is still a noteworthy presence of these chemicals. It could indicate that you have been exposed to PFAS at a level that is higher than typical background exposure, but not to the extent that would trigger concerns for significant health risks, as seen with higher levels.

Next Steps for Intermediate Results

If your NASEM Recommended Summation result is "intermediate," it’s important to discuss the result with your healthcare provider. They can provide guidance on whether further monitoring or steps to reduce PFAS exposure are necessary. While this result does not indicate an urgent risk, it could be a signal to evaluate lifestyle factors, such as reducing exposure to PFAS-containing products (e.g., nonstick cookware, water-repellent clothing, or certain foods) or reviewing water quality if you live near potential contamination sources.

Your doctor may recommend periodic testing or other actions to minimize future exposure to PFAS.

Conclusion

An "intermediate" result on the NASEM Recommended Summation scale indicates moderate PFAS exposure. While this is not typically cause for immediate concern, it is an opportunity to monitor and assess your exposure levels and take preventive steps if necessary. Always consult with your healthcare provider to better understand your results and any appropriate next steps.

NATURAL KILLER CELLS CD3-CD16+CD56+ (ABS)

Lymphocyte Subset Panel 2

Optimal range:   70 - 760 cells/uL

The Natural Killer Cells CD3-CD16+CD56+ (ABS) test is an advanced diagnostic tool with significant implications in the fields of immunology, oncology, and reproductive medicine. Natural Killer (NK) cells, a critical component of the innate immune system, play a vital role in the body’s first line of defense against tumors and virally infected cells. This test quantifies the absolute number of NK cells in the blood, specifically identifying the subset characterized by the absence of CD3 and the presence of CD16 and CD56 markers. High or abnormal levels of these cells can be indicative of various health conditions.

Neisseria gonorrhoeae, NAA, Urine

Sexually transmitted disease

Reference range:   Negative, Positive

What is gonorrhea?

Gonorrhea is a sexually transmitted disease (STD) caused by infection with the Neisseria gonorrhoeae bacterium. N. gonorrhoeae infects the mucous membranes of the reproductive tract, including the cervix, uterus, and fallopian tubes in women, and the urethra in women and men. N. gonorrhoeae can also infect the mucous membranes of the mouth, throat, eyes, and rectum.

How do people get gonorrhea?

Gonorrhea is transmitted through sexual contact with the penis, vagina, mouth, or anus of an infected partner. Ejaculation does not have to occur for gonorrhea to be transmitted or acquired. Gonorrhea can also be spread perinatally from mother to baby during childbirth.

People who have had gonorrhea and received treatment may be reinfected if they have sexual contact with a person infected with gonorrhea.

Nervonic 24:1 n9

Metabolimix+, Genova Diagnostics

Optimal range:   1.1 - 1.8 wt %

Nervonic acid (NA) is an omega-9 MUFA with a 24-carbon backbone and one double bond (24:1n9). It is a very important fatty acid in the white matter of the brain and is responsible for nerve cell myelin biosynthesis. There are small amounts of NA in cooking fats, vegetable oils and borage oil. It can also be synthesized in the body by elongating oleic acid (which is essentially desaturated stearic acid). NA is essential for the growth and maintenance of the brain and peripheral nervous tissue enriched with sphingomyelin.
