Urine test dilution
Common Questions and Answers about Urine test dilution

Dilution. Intake of fluid during the day dilutes the urine and makes it to where it won't pick up the hormone. Low sensitivity tests also influence it, as they need high levels of the hormone present to detect it. If you read the pregnancy test box it should say first morning urine is recommended as well.
Now I am worried if I got a negative test due to the dilution of the urine sample due to increased quantity.
Could anyone here confirm about the accuracy of the PCR test in case the sample got diluted? Can I rely on my test results? I can't confirm it from the lab as it is really far and I don't have any contact info.
Please help me.
hi i took two pregnancy tests int the evening, one to test and the second to confirm. the first test came up with a dark positive response line almost straight away, and the second was fainter but still there, i asume because i had already peed and then my urine was slighlty diluted after drinking lots of water. my question is as i have irregular periods would i be at least 10 dpo? me and boyfriend trying to work out when we conceived.
m almost nearly deficient and I eat healthy). Ferritin was a little low (not abnormal, but supplements recommended). There were leukocytes in my urine (2+? i don't know what that means).

If pregnancy is suspected, you should take a pregnancy test with first morning urine or see your doctor for blood testing. If you ARE pregnant, it's important to see where the pregnancy is. Your odds of it being Ectopic are higher after a ligation is done, and would require immediate medical attention.

I got my test result early this morning and don't know how to interpret them.
ASSAY Result Dilution Range
hTSH_II 8.698 uIU/mL Undiluted
Free_T4 0.77 ng/dL Undiluted 0.71-1.85
Those this results mean that I'm Hyper or Hypo?
Because of the immunosuppression associated with Cushing’s disease, evidence of bacterial infection may be present as well or such evidence may be concealed by the dilution of the urine. Ideally urine should be CULTURED if it is too dilute to reliably detect white blood cells or blood. Recent studies have shown that 20% of dogs with Cushing’s disease have an inapparent bladder infection." <== that is probably why your doctor suspect's Cushings.
it is not 250iu/ml, the test was made without dilution and it says superior to >250iu/ml.
40 or less BUT just because your is high does not mean you have an autoimmune condition associated with the test. It is possible to test positive and not have any of the associated conditions. I am an example of this in that I tested through the roof for the antibodies for scleroderma but I do not have that condition.
Are you taking any medications? Some meds can affect the results of the test.
so since there are no diluitions the values very high are extremely precise, abbott architect needs dilution and if the tech makes a mistake during diluition there maybe an error of 500-1000iu/ml
LabCorp recommends 20-30 ml for STI urine test. Half a container of the typical urine cup is 60 ml. If submitting 60 ml what is the risk of a false negative due to a dilluted specimen.
If results are truly negative what other STI could cause these issues?
Would a single act of unprotected intercourse with GF put her at risk for an STI, i know the answer is yes but what is the likely hood of infecting her?
Could I have transferred fluids/bacteria while changing condoms?
Hi nved.
1:80 is "considered" as negative or as there's little diagnostic value
even if it is on the positive.
Negative would technically be the last dilution where there's no flurescense observed under the mircoscope and in your case it would be 1:160 (the amount of dilution doubles each time), but the one reported is the last one where there's observable presence of flurescence.
It can be confusing!
Are you gluten free and /or grain free and very low carb?
