For HIV in the USA, Not in Care Exceeds the Undiagnosed — Solutions Welcome

In last week’s post, I asked about two of the key components of the HIV care cascade — the “undiagnosed” vs the “diagnosed but not in care,” and which group was larger in the USA. Here are your answers as of now: The people who read this site are a pretty knowledgeable group when it comes to […]

CD4 Cell Count at Presentation: A Figure with a Depressingly Small Upward Slope

You know how to make an ID/HIV specialist angry? Frustrated? Sigh loudly? Tell a clinical anecdote that involves “late” presentation of HIV diagnosis, in particular someone who has been seeking medical care for various ailments for months or even years without getting tested. You know — it goes something like this: “He was seen 3 years ago for […]

Let’s Move the HIV Testing Algorithm Into the 21st Century

As I’ve written before, the most widely used testing algorithm for HIV — enzyme immunoassay followed, if positive, by Western blot confirmation — is long overdue for an update. A brief review why this is the case, and also why sticking with it is so problematic: Immunoassays have become progressively more sensitive, especially when paired with p24 […]

The U.S. Preventive Services Task Force Recommends HIV Screening — And Why is This News?

A flurry of coverage recently appeared about the U.S. Preventive Services Task Force’s recommendation for one-time HIV screening for all Americans, ages 15-64. Some might wonder why this is news — um, hasn’t this been recommended now for years? — and I think I’ve figured it out. Let me start by relaying that every ID/HIV specialists can tell […]

It’s Time to Dump the HIV Western Blot

Hard to believe, but we have to get rid of the HIV Western blot — at least as our HIV confirmatory test. Here’s why (case adapted from several seen the past few years; I’m sure most of you have seen similar): 30-year-old man, high risk for HIV. He’s worried he might have become infected due to recent […]

Home HIV Test Big News — But Why? And What Impact Will It Have?

The recent FDA approval of a home HIV antibody test (OraQuick In-Home HIV Test) was covered just about everywhere. It’s an oral swab test, takes 20-40 minutes, and will be available over-the-counter. How big a news story was it? Several hundred sources featured it on the day of the announcement, and the total count is now well over a thousand […]

HIV Testing Roundup, and a Brief Rant

I’ve written so many times about HIV testing that a complete list of the headlines fills two full web pages. But since the last entry on the topic was more than a month ago, one might think I’ve lost interest in the topic. Never! Three items on the HIV Testing radar, two national, one local. First, for a classic […]

News on HIV and HCV Testing, and in Praise of Accurate Screening Tests

Two recent news items reminded me how lucky we are to have some very accurate screening tests for certain infectious diseases. The news: An expert FDA panel backed approval of the first true home test for HIV, the OraQuick mouth swab test. Approval of OraQuick for home use may occur later this year. While home testing for […]

Common Sense on HIV Testing

There’s an editorial in today’s Boston Globe that concisely (188 words) describes the problems with both the current and proposed HIV testing laws in Massachusetts. I’ve not been shy about the fact that I agree with every word of this piece. And though I strongly recommend reading the whole editorial — it’s very well written — if you […]
