What should my levels be for a pregnancy blood test to show im pregnant too them?

Testing: You are asking the wrong question. HCG increases daily after a viable pregnancy is old enough to be big enough to have blood and chemicals. That transition occurs at about ten days post conception. It also corresponds with the time a period is due and it stops the period leading to a missed period and the first real symptom of early pregnancy. That is the sign to look for to know when to test. ...Read more

Pregnancy (Definition)

When your due date arrives, you will be more than ready to have your baby! Most women deliver the baby somewhere between 37 and 42 weeks. According to the American College of Obstetricians and Gynecologists, only 5% of babies arrive on the exact due date. Approximately 7% of babies are not delivered by 42 weeks, and when that happens, it is referred to ...Read more

Will nicotine show up in a blood test?

Will nicotine show up in a blood test?

Yes: If they are specifically testing for it. Cotinine, the main metabolite of nicotine, is generally tested for in urine, where it is present in larger amounts than in blood and is easier to find. However, it can be detected in blood as well. If you are a smoker, the easiest way to "beat" the test is to stop smoking! Please consider stopping and getting help doing it if you need to. ...Read more

I'm not a regular smoker but I smoked the other day. Will the nicotine show up in my nicotine blood test a week from now?

I'm not a regular smoker but I smoked the other day. Will the nicotine show up in my nicotine blood test a week from now?

If you are being: Tested, and you know you are being tested, then why would you smoke a cigarette? Most insurance companies and others who test for nicotine use urine rather than blood, but in any case a single cigarette would give you metabolites in blood for a handful of hours, and at most a day. You need to look at your impulsivity and judgment if you get tested regularly and still do it. Counseling might help. ...Read more

2-4 days: The clearance rate for nicotine from blood is between two to four days. So, if you can refrain from smoking for a week prior to the test, it is unlikely that a medical screening test would be sensitive enough to detect that you were a smoker.
If you are smoker havy smoker for long time it my take longer. ...Read more

I believe I am pregnant, my LMP was dec 10. Blood test on jan 13 was negative. My last pregnancy also did not show positive until 6 wks. Why?

Insensitive test: Every commercial pregnancy test as a threshold of HCG present in your urine that will convert the test to positive. It is not zero. Thus blood pregnancy tests are more accurate as ANY HCG can be detected no matter how small. ...Read more

Could the nicotine from a washed shisha (0.05%) that I smoked yesterday show up in my blood test?

Could the nicotine from a washed shisha (0.05%) that I smoked yesterday show up in my blood test?

Impossible to say: First, am not sure anybody is doing blood tests for nicotine or cotinine, because neither stays in blood more than a few hours. Urine testing is the gold standard, and remains positive for about 2 days after a single exposure. There is nothing healthier about using a hookah, and you should strongly consider discontinuing your tobacco habit before it harms your health, rather than fear of a test. ...Read more

How many days past ovulation will a blood test show pregnancy?

How many days past ovulation will a blood test show pregnancy?

About two weeks: The blood test should be most accurate about 14 days after ovulation. It's possible to get a positive blood or urine pregnancy test earlier than this. But it's not as reliable as the 'two week wait'. A HCG 'trigger shot' can give you a false positive pregnancy test if you test too early, as well. ...Read more

Which blood test will show pregnancy results and after how many days of missing of periods it should be done?

HCG -One day after: Conception, as defined by the generation of a fertilized ovum, occurs within day or so of the sex. However, it takes about two weeks for the embryo to make enough HCG to produce a positive pregnancy test. Blood test may be done a day after a missed period. Home pregnancy tests should be done 4-5 days after the missed period. Use first morning urine and follow instructions for the test carefully. ...Read more

For a new patient blood test, will nicotine show up?

Later: When your period is due, a pregnancy test will be positive if you have conceived. You have done the pregnancy tests too soon after having sex for the test to be positive. It takes 10 to 14 days after conception for the test to turn positive. ...Read more

Depends when test: I s done. If done within a few minutes or perhaps an hour of that puff, it might show up. If done many hours or days later, it should not. Most testing is done through urine rather than blood, because nicotine metabolites can be detected in higher amounts and for longer periods of time in urine. ...Read more

Please tell me will the nicotine from a washed shisha (0.05%) that I smoked yesterday show up in my blood test?

No way to know: What you mean. The method by which you smoke, whether cigarette, pipe, cigar or a hookah does not change the amount of nicotine you take in. Unless you drank the water from the hookah, whatever nicotine you took in was in the smoke, and depends on how much you smoked. Odds are your test will be positive. ...Read more

Blood test results back yesterday. Doc says it shows very low levels of pregnancy hormones, need to get another 1 next week. What courses that result?

Change in hCG: An early pregnancy produces rapidly increasing levels of the pregnancy hormone hcg. How that level changes over the course of a couple days or more tells a lot about the health of the pregnancy, even before it can be seen on ultrasound. ...Read more

Can hcg levels 4.2miU/ml show up 28 days after sex on blood test? Does every woman have hcg levels regardless of pregnancy or not?

Can hcg levels 4.2miU/ml show up 28 days after sex on blood test? Does every woman have hcg levels regardless of pregnancy or not?

Less than 5: An HCG value of less than 5 28 days after sex essentially rules out pregnancy. Normal levels in non-pregnant state are less than 5. A level of greater than 25 is diagnostic of pregnancy. Between 5 and 25, the test needs to be repeated in a week or so.
As I mentioned earlier, from the information you provided your highly unlikely to be pregnant. ...Read more

Too early: Conception, as defined by the generation of a fertilized ovum, occurs within day or so of the sex. However, it takes about two weeks for the embryo to make enough HCG to produce a positive pregnancy test. Blood test may be done a day after a missed period. Home pregnancy tests should be done 4-5 days after the missed period. If the result is negative re do the test in 4-5 days, unless you get a period before then. Use first morning urine and follow instructions for the test carefully. ...Read more

Had my tubes tied for 2yrs now missed 4months of my period urine blood test negative can it be a tubal pregnancy that's why it doesn't show on the test?

Hormonal Etiology: I suspect your amenorrhea is most likely hormonal involving your pituitary-hypothalamus axis or the ovary. Falling serial HCG levels are usually seen in ectopic pregnancy and its level is usually lower than that of a normal intrauterine pregnancy. See your doctor for confirmation.. ...Read more

Misssed period mid-July; nausea and vomiting until last Friday: heavy Bleeding commence cont. With huge clots and vaginal tissue; still bleeding (pv) now; blood test bHCG level at 4000 today. Sonogram shows no uterine gestation. Is this ectopic?

Misssed period mid-July; nausea and vomiting until last Friday: heavy Bleeding commence cont. With huge clots and vaginal tissue; still bleeding (pv) now; blood test bHCG level at 4000 today. Sonogram shows no uterine gestation. Is this ectopic?

Maybe: Would need to see another level or two to confirm if dropping. If its an ectopic the level will often plateau, whereas if you passed most of the pregnancy already the level will drop. If you haven't seen a gynecologist, you need to and if bleeding severe, an ER visit may be needed. Molar pregnancy is also possible. ...Read more
