Question 1

how common is the variant hook effect?

Accepted Answer

Unclear question: Are you referring to the "hook" effect in immune assays? If yes, the frequency varies with the clinical situation. A common time for the hook effect is in secondary syphilis. Any test in which there is very high differential in the amount of antigen and antibody may result in hook effect; also called prozone phenomenon.

Question 2

pee was very diluted when i took the positive tests, but the fmu tests were negatives. is this the hook effect?

Accepted Answer

Unlikely: It is more likely that the initial test may not been done properly. If you have doubts, it would be prudent to get a blood test for HCG level.

Question 3

Accepted Answer

Question 4

whats the hook effect on hcg urine tests? does the hook effect happen on blood also?

Accepted Answer

: Hook effect affects blood tests more than it affects urine tests. Hook effect refers to the apparent low levels when the actual levels are extremely high. Urine tests are not quantitative measures and yes/no answers are not affected as much.

Accepted Answer

: Pregnancy is not possible in described circumstances. Try to address your anxiety with your primary care doc.

Question 6

my period is late. i would be 9 wks from lmp tomorrow. i am testing negative w/blood although i did have a faint + on urine. could this be hook effect?

Accepted Answer

Unlikely in general: A urine pregnancy test, done correctly, gives a reliable result by 3 weeks after sex (3 weeks after when conception might have occurred) or 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon and thus lead to a repeat test. If a woman gets her normal regular period, then she is not pregnant, and a test is not needed.

Question 7

is hooks effect seen in quantitative beta hcg blood test? does it have to be diluted to check if high levels if present?

Accepted Answer

No: The effect is only seen in some one step HCG urine tests. Serum quantitative tests are not subject to the effect.
