That is relatively cheap to include an hCG piece to testing.

A pregnancy test detects level of hCG in a woman’s urine. The placenta beginning to relax hCG as early as 14 work after fertilization.

In cases where drug tests are sent to the laboratory a gas chromatography and mass spectrometry tool breaks down the sample right into all its components. Because that confirmations a laboratory technician will emphasis on the analyte associated with the hopeful test strip, but all of the compounds are identified. A high level that hCG would be recognized fairly quickly.

So the is true that drug testing would determine pregnancy in situations when service providers test for pregnancy or samples are sent out to a lab. The assays uncovered in drug test cups and also used in activities immunoassay tests perform not detect hCG though.

What are the differences in Men and also Women’s Urine

In the rare case a lab technician or clinical review officer doubt a subject has used a urine sample from who of opposing sex the sample have the right to be put through additional analysis to assistance their suspicions. Even though a medicine test itself cannot recognize gender, various other tests have the right to indicate gender.

The biggest differences in every sex’s urine space trace hormones, however there are indicators that may cause a laboratory technician to end up being suspicious and investigate further.


Women’s urine have the right to contain hCG (the analyte supplied to recognize pregnancies).Women’s urine deserve to be contaminated by blood throughout menstruation.


Men procedure alcohol differently. Greater concentrations that dehydrogenaze are present after consuming alcohol.Men have higher muscle fixed which have the right to increase creatinine levels.Male samples have the right to contain traces the sperm or pre ejaculate, but females deserve to too for 8-12 hrs after sex.

Foreign issue such as blood and semen are good indicators that gender, but are much from definite due to the fact that men have the right to have blood in their urine and also women deserve to have masculine semen in their urine after sex.

The most basic hormone to identify a person’s sex in to pee is testosterone. Men produce less testosterone together they age, but will always excrete significantly more testosterone in your urine. Marijuana has been shown to suppress the production and secretion the testosterone and other androgens. A study carried out by the Worcester foundation for speculative biology uncovered that males excrete 28-250 μg that testosterone in your urine, while women excrete 2.4-8μg.

Testosterone level in Urine

Sex / AgeAVG Testosterone Levels
Male 18-28171 μg (range 65–250)
Male 30-3589 μg (range 45–150)
Male 42-5581 μg (range 28–159)
Female 23-376 μg (range 2.4–8)

Can drug Blood & Hair medicine Tests detect Gender?

It is nearly impossible come adulterate or substitute hair or blood samples throughout a drug test because a subject has to physically present themselves to have samples taken. A technician will certainly confirm the identification of the topic at the time of sample donation. Any anomalies that shown a different gender would certainly be investigated as a health concern instead of possible tampering.

However, the exact same hormones the are present in pee are present in a person’s blood, and also DNA from human being hair can be provided to determine a person’s gender.

Hair samples can give an indication of gender simply by the length and treatment when examined under a microscope, but nuclear or mitochondrial DNA would certainly be essential to determine gender with a hair sample definitely.

Considerations once Testing different Genders

Even despite the basic mechanisms of exactly how a medicine test functions is the exact same whether friend are testing a masculine or female, there space some differences you may want come account for. For instance women process alcohol slower 보다 men. It would be less complicated for a woman to have actually some drink at night and still have alcohol passing through their system the next morning.

Another factor to consider is that women have a much higher body fat percent than men. A healthy and balanced middle aged male has a human body fat percent of 20% when a healthy female of the same period has a body fat portion of 30%. Medicine or metabolites that bind to fat tissues deserve to be detected much longer in an individual with a higher body fat content.

GenderBody TypeBF % period 20-39BF % age 40-59BF % period 60-79

This doesn’t typical that a woman that you should alter results because that females, but there are many instances once this knowledge is useful. For example after a failed drug test you can expect ladies to have actually a slightly longer detection time for drugs that have an affinity for fatty tissue. It can help with scheduling retests, confirming patient statements, and advising clients around detection times.

Will girlfriend Get captured if You usage Urine indigenous the the contrary Sex to Cheat a drug Test?

Using urine indigenous the the contrary sex to happen a medicine test will go unnoticed in the vast majority of drug screens since assays just detect the metabolite they room designed for. A male utilizing a pregnant female’s to pee would rise the likelihood of gift caught due to the fact that of the hCG content.
