blood sampling

blood sampling

laboratory examination of samples of blood. These are usually collected from an appropriate vein, but arterial samples are required for some special techniques. Collection is by a closed method, either a hypodermic syringe or a vacuumized container. The site of collection varies with the species and the circumstances. The sample may be clotted, for serum estimations, or collected with an anticoagulant for examinations on plasma or whole blood.

Patient discussion about blood sampling

Q. I am 15 weeks pregnant. I had my NT scan and blood draw today. Iam using my Hubby user name here.I am 15 weeks pregnant. I had my NT scan and blood draw today. I doubt whether I am in a risky state because I read in medical journal that women with certain amount of risk go for second trimester screening and not healthy pregnant women. Is it so? Please clarify?

A. There's something called an integrated sequential screening. You have the NT scan and blood draw in your first trimester, and then go back for an additional blood draw in your second trimester. They then calculate a unified result and present the results in the second trimester. Several other sources mentioned that often a high risk based on the NT scan and the first blood draw will prompt a diagnostic test. Yes, women with low or acceptable risk go on for the second trimester screening.
