What if hCG is negative but pregnancy is suspected?

A negative hCG result means that it is unlikely that a woman is pregnant. However, tests performed too early in a pregnancy, before there is a significant hCG level, may give false-negative results. The test may be repeated in one week if there is a strong possibility of pregnancy.

Can you be pregnant with negative hCG test?

The simple answer is yes, you could still be pregnant even with a negative test, depending on when you took it, but there are also other reasons your period could be late. A pregnancy test detects HCG levels in your urine which increase the longer you are pregnant.

What does internal control mean in a pregnancy test?

Internal procedural controls are included in the test. A red line appearing in the control region (C) is the internal procedural control. It confirms sufficient specimen volume and correct procedural technique. A clear background is an internal negative background control.

What is internal QC test?

QC testing is performed within a laboratory to monitor and ensure the reliability of test results produced by the laboratory. Control materials (usually liquid controls) are used to monitor the test system and verify that quality patient test results have been attained.

What is positive QC?

Positive Quality Control (QC) Slides. Positive control slides are used to ensure that all techniques were executed properly and resulted in successful staining.

What is an internal QC?

Internal quality control (IQC) is a process for checking that the uncertainty at validation does not deteriorate after validation, that is, when the method is in routine use.

What does hCG control positive mean?

A positive hCG means that a woman is likely pregnant. However, false-positive tests can occur if a woman is post-menopausal or taking hormone supplements. The blood level of hcG in a woman with an ectopic pregnancy usually rises at a slower rate than normal.

Why internal quality control is important?

Internal quality control (IQC) ensures that factors determining the magnitude of uncertainty do not change during the routine use of an analytical method over long periods of time. Together with validation, IQC forms the mainstay of quality practice in chemical analysis.

What is the purpose of QC?

Quality control involves testing units and determining if they are within the specifications for the final product. The purpose of the testing is to determine any needs for corrective actions in the manufacturing process. Good quality control helps companies meet consumer demands for better products.
